Custom renameParticpant dialogue with "FATALERROR: No input element provided"

I am creating a custom renameParticpant to rename an Eclipse project's launch configuration files, and to change the APPNAME variable in the Makefile. The Makefile side works 100% of the time, but attempting to rename the launch configs causes the following error to occur:
<FATALERROR
FATALERROR: No input element provided
Context: <Unspecified context>
code: none
Data: null
>
This error occurs when the changes are being validated at the following line in org.eclipse.ltk.core.refactoring.PerformChangeOperation [line: 248].
fValidationStatus= fChange.isValid(new SubProgressMonitor(monitor, 1));
Below is a screenshot of the variable view. I suspect that my compositeChange is not in the correct format or is missing some information, however; the error dialogue and logs don't give any helpful information.
Debugger variable view of fChanges
The following is relevant code snippets:
// This one sparks joy (it works great, 100% success)
final HashMap<IFile, TextFileChange> textChanges = new HashMap<IFile, TextFileChange>();
// Stuff gets put inside
textChanges.put(makefile, changeAppname);
// This one does not spark joy (it runs, but results in an invalid Change)
final HashMap<IFile, RenameResourceChange> renameChanges = new HashMap<IFile, RenameResourceChange>();
// Stuff gets put inside
RenameResourceChange renameChange = new RenameResourceChange(
launch.getFile().getProjectRelativePath(), newLaunchName);
renameChanges.put(launch.getFile(), renameChange);
// This is where they get added to the hashmap.
CompositeChange result;
if (textChanges.isEmpty() && renameChanges.isEmpty()) {
result = null;
} else {
result = new CompositeChange(
String.format("Rename project references and dependencies for %1$s", proj.getName()));
for (Iterator<TextFileChange> iter = textChanges.values().iterator(); iter.hasNext();) {
result.add(iter.next());
}
for (Iterator<RenameResourceChange> iter = renameChanges.values().iterator(); iter.hasNext();) {
result.add(iter.next());
}
}
return result;
I looked into adding or generating a changeDescriptor, however that seems like the wrong approach.

Java executable .jar file not working properly after compiling in NETBeans IDE

I am exporting a .jar file from a GUI built in Netbeans IDE. It works fine within Netbeans but once it is exported, some logic in the code does not execute properly.
I have tried debugging by running test cases displaying which items are passing through the if clauses. It seems to work well in IDE but not when it is run through .jar file.
for(Chamber chamber: chs)
{
if(!scheduledTools.containsKey(chamber))//unscheduled chambers
{
JOptionPane.showMessageDialog(this, chamber.getName()+": is unscheduled");
model.addElement(chamber.getName());
}
else//scheduled
{
if((scheduledTools.get(chamber).size()/range) > .25)
{
System.out.println("Range: " +range+" Scheduled: " +scheduledTools.get(chamber).size());
System.out.println("Cannot use this chambers:" +chamber.getName());
JOptionPane.showMessageDialog(this, chamber.getName()+": Cannot use this chamber");
}
else{
System.out.println("Scheduled but can use"+chamber.getName());
altModel.addElement(chamber.getName());
}
}
}
alternateChambers.setModel(altModel);alternateChambers.setSelectedIndex(0);
suggestedChambers.setModel(model);suggestedChambers.setSelectedIndex(0);
if(altModel.size()>1){JOptionPane.showMessageDialog(this, "Scheduled but can use these chambers:"+altModel);}
After making the necessary queries in seekDates method below:
private void seekDates(ResultSet rs) throws SQLException
{
ArrayList<String> entries;
//get how many dates we have so we can update progressbar
int results = 0;
setProgress(results);
if(rs.last()){results=rs.getRow();rs.beforeFirst();}
// processing returned data and printing into console
while(rs.next()) {
String scheduledChamber = rs.getString(2);
for(Chamber chamber : chambers){
//if the scheduled tool is a thermal chamber
//chambers get listed so far
if(!scheduledChamber.trim().toLowerCase().contains(chamber.getName().toLowerCase()))
{}//print chambers im not saving
else{
if(scheduledTools.containsKey(chamber))
{
//if key already used, just grab the list and add date
entries = scheduledTools.get(chamber);
entries.add(rs.getString(1).split(" ")[0]);
}
else
{
//if chamber hasnt been saved, add chamber and date
entries = new ArrayList<String>();
entries.add(rs.getString(1).split(" ")[0]);
scheduledTools.put(chamber, entries);
}
//System.out.println("Just saved this chamber:" +scheduledChamber+" with this date:" +scheduledTools.get(chamber));
}
;
}
publish(rs.getRow());
Thread.yield();
setProgress(100*(rs.getRow()/results));
}
}
The GUI should display the chambers found in the queries in one text field while displaying the rest of the chambers in another text field.
When I run this in the IDE. I get the correct outcome but once I compile using the package-for-store option in the build.xml file, the outcome then just lists all of the chambers in one text field.
In the .jar file, it seems that all of the chambers only satisfy the first if clause and none of the others.

Assertion failure in NSEvent?

thanks for taking the time to read this. I'm fairly new to JavaFX and have a weird error in my compiler that I would like some insight on.
Here's the error:
2018-09-13 19:09:36.387 java[8040:660455] unrecognized type is 4294967295
2018-09-13 19:09:36.387 java[8040:660455] *** Assertion failure in -[NSEvent _initWithCGEvent:eventRef:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/AppKit/AppKit-1652/AppKit.subproj/NSEvent.m:1969
Here is the code I am working with:
This is in a .java file named applicationSettings
public static double lookupUser(String name, String password) throws IOException {
InputStream inputStream = applicationSettings.class.getResourceAsStream("/files/users.xlsx");
XSSFWorkbook workbook = new XSSFWorkbook(inputStream);
XSSFSheet sheet = workbook.getSheetAt(0);
Integer lastRow = sheet.getPhysicalNumberOfRows();
int currentRow = 1;
while(currentRow < lastRow) {
if(sheet.getRow(currentRow).getCell(0).getStringCellValue().toLowerCase().equals(name.toLowerCase())) {
if(sheet.getRow(currentRow).getCell(1).getStringCellValue().toLowerCase().equals(password.toLowerCase())) {
double accessLevel = sheet.getRow(currentRow).getCell(2).getNumericCellValue();
System.out.println(accessLevel);
return accessLevel;
}
}
currentRow++;
}
return 4.0;
}
}
This is in a .java file named loginScreen
EventHandler<ActionEvent> loginClicked = new EventHandler<ActionEvent>() {
public void handle(ActionEvent event) {
double userFound = 0.0;
try {
userFound = applicationSettings.lookupUser(usernameField.getText(), passwordField.getText());
} catch (IOException e) {
e.printStackTrace();
}//END of Try/Catch
if(userFound == 1.0) { //1 is Admin Access
//TODO: Implement Login
System.out.println("Admin Login");
errorLabel.setVisible(false);
}else if(userFound == 2.0){ //2 is Elevated Access
//TODO: Elevated Access
System.out.println("Elevated Login");
errorLabel.setVisible(false);
}else if(userFound == 3.0){
//TODO: Basic Access
System.out.println("Basic Login");
errorLabel.setVisible(false);
}else{//Show Error
errorLabel.setVisible(true);
//TODO: Show Error
}//End If Statement
}
};
My Excel File is basically structured like this:
NAME PASSWORD ACCESS LEVEL
So for my login it would be like:
Trey Carey March3199; 1
This isn't going anywhere besides by church where it's not really doing anything besides automating some tedious tasks, so security isn't an issue.
Also, if there's anyway I can clean up some of these if statements and my code in general I would appreciate any tips or help!

Edit 2 13.11.2018:
This bug has been officially fixed now in JavaFX 12, was backported to JDK8 and approved to be backported to JFX 11. You can have a look at the bug report to find more information about it.JDK-8211304 Here is a link to the changes they've made. openjfx I'm personally not sure about the current license situation of JDK8 so I would advise to switch to the newest OpenJDK and OpenJFX if possible.
Hey there I'm experiencing the same issue you have and I can constantly reproduce it. The issue appears for me on JavaFX on macOS 10.14. You can simply create an application with a button that opens a second stage. If you invoke stage.showAndWait() (could be related to anything that holds the thread) on the second stage and then switch focus between different applications (I just alt-tab between my JavaFX app and Safari), the JavaFX Application crashes. Also reproducible in any IDE.
I actually found a bug report on the OpenJDK/OpenJFX bug tracker but there isn't much going on at the moment. JDK-8211137 Mac: JVM Crash due to uncaught exception
I don't have a solution yet as I'm having troubles pinning down the exact problem but I found a workaround that works in my specific case.
Edit:
If I'm using "stage.show()" I'm only getting the error but when using stage.showAndWait() or anything that does some kind of waiting loop, the application completely crashes.

Is it possible to call quickfix solutions(eclipse) for specific(error/s)?

I have a program which scans a Java file for errors. I call the compiler from Eclipse and run a scan on the Java file and get the line numbers, start position and end positon as output. I have written a program to extract the error from the file.
What I want to do is to have access to the quickfix component in eclipse, have a list of possible fixes for the problem, and print that list to the console.
Below is a portion of the program of how I called the compiler and got the details printed on the console:
Iterable fileObjects = fileManager.getJavaFileObjectsFromStrings(
Arrays.asList(fileToCompile));
CompilationTask task = compiler.getTask(null, fileManager, listener, null,
null, fileObjects);
Boolean result = task.call();
if(result == true) {
System.out.println("Compilation has succeeded");
}
myerrors = listener.getlistofErrors();
for (CaptureErrors e : myerrors) {
System.out.println("Code: " + e.getCode());
System.out.println("Kind: " + e.getKind());
System.out.println("Line Number: " + e.getLinenumber());
// System.out.println("Message: "+ e.getMessage(Locale.ENGLISH));
// System.out.println("Source: " + diagnostic.getSource());
System.out.println("End position"+ e.getEndposition());
System.out.println("Position: "+ e.getPosition());
System.out.println("\n");
}
class MyDiagnosticListener implements DiagnosticListener {
List<CaptureErrors> errors = new ArrayList<CaptureErrors>();
public void report(Diagnostic diagnostic) {
CaptureErrors single_error = new CaptureErrors(diagnostic.getCode(),
diagnostic.getKind(), diagnostic.getLineNumber(),
diagnostic.getMessage(Locale.ENGLISH), diagnostic.getPosition(),
diagnostic.getEndPosition());
errors.add(single_error);
}
public List<CaptureErrors> getlistofErrors() {
return errors;
}
}
I also have a program to go to the line numbers and extract the text(error) at specific positions.
How can I call eclipse quickfix solutions for the specific errors that I find?

Yes, it is possible. The exact details are a bit larger than can easily be encompassed in even a StackOverflow answer.
Eclipse is extended through the use of plug-ins. A "Hello World" plugin is detailed here, and after you get through the initial learning curve, you can download other plugins to get a feel for how eclipse works internally.
I imagine that you would do well to examine the current code highlighting capabilities of eclipse and read the source code for those plugins as a guide, but only after you get some idea of how plugin development works.

Android / Java : GC_CONCURENT when creating many String's

I'm blocking with a problem from a few days. I've found some similar posts but still didn't understanding the problem of my code.
In fact, I'm reading a file (18,4Kbytes) which is containing SQL queries. So the only thing I want to do is read the file and execute the queries.
I've no problem reading the file, the problem occurs when after having executed all the queries (if I don't execute it, it works but it's not the deal!)
So here's my code (between try / catch for IO Exception):
InputStream in = ctx.getAssets().open("file.sql");
ByteArrayBuffer queryBuff = new ByteArrayBuffer(in.available());
String query = null;
int curent;
while (-1 != (curent = in.read())) {
queryBuff.append((char) curent);
if (((char) curent) == ';') {
query = new String(queryBuff.toByteArray());
db.execSQL(query);
queryBuff.clear();
query = null;
}
}
in.close();
queryBuff.clear();
And my GC_CONCURENT occurs when there is "new String" in the loop, after the end of the loop.
Thanks !
EDIT :
I'm a little annoyed, because my memory-leak didn't occurs in this part of code but in a part of code executed laterly (don't know what for now) but my problem wasn't a problem, app worked properly in fact...
Sorry !
