Missing class from package within Netbeans when using Spire.Doc.jar for docx files

I downloaded and installed the free Spire.Doc.jar file to work with .docx files. When I run it within Netbeans the functionality works fine however when I attempt to build the program I am getting the following error:
warning: Supported source version 'RELEASE_6' from annotation processor 'org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor' less than -source '1.8'
Note: Creating static metadata factory ...
error: com.sun.tools.javac.code.Symbol$CompletionFailure: class file for com.spire.doc.packages.spryOb$1
not found
An annotation processor threw an uncaught exception.
Consult the following stack trace for details.
java.lang.RuntimeException: com.sun.tools.javac.code.Symbol$CompletionFailure: class file for com.spire.doc.packages.spryOb$1 not found
I have added the .jar file to my class path however there appears to be a class file missing from the com.spire.packages location.
Does anyone know if this is a Netbeans issue or does it look like there is an issue with the .jar file? I find it strange that it works when I run it within Netbeans but the above error occurs when I attempt to build the project.

I managed to get my application to build. What I had to do was remove the following code from my class and then it worked:
document.getMailMerge().MergeImageField = new MergeImageFieldEventHandler()
{
#Override
public void invoke(Object sender, MergeImageFieldEventArgs args)
{
mailMerge_MergeImageField(sender, args);
}
};
private static void mailMerge_MergeImageField(Object sender, MergeImageFieldEventArgs field)
{
String filePath = field.getImageFileName();
if (filePath != null && !"".equals(filePath))
{
try
{
field.setImage(filePath);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
I'm not sure why it didn't work with this included however I got this code from the following website:
https://www.c-sharpcorner.com/article/how-to-perform-mail-merge-in-word-document-in-java/
therefore I will inform them in case this happens to someone else in the future.

Bug in Netbeans IDE Dev 201802140002?

Here is the code that's expected to produce error:
public class App {
public static void main (String[] args) {
tick();
}
public static void tick () {
System.out.print("hi");
Note that the closing angled bracket of both, the method tick() and class App is missing. Although the IDE indicates this error while writing code, this compiles and runs just fine. It doesn't look like an issue with Java (or my OS) as doing javac in the command line surely does fail.
What's even funnier...the following code throws a Runtime exception after successfully executing tick():
public class App {
public static void main (String[] args) {
tick();
public static void tick () {
System.out.print("hello..");
Here I skipped closing bracket of main too.
I have installed the development version of Netbeans that has support for Java 9.

[This is a comment more than an answer, but I wanted to include screen shots to show that I cannot reproduce either issue.]
An interesting problem. I just downloaded the most recent nightly build (NetBeans Dev 201803060002) and built your code using Oracle JDK 9.04.
Neither of your code examples would compile for me. For the first example the error for the final line was "reached end of file while parsing System.out.print("hi");". Here is a screen shot:
For the second example, where you removed the closing bracker of main() the additional error reported was "illegal start of expression public static void tick () {":
I suggest that you try the following:
Create a new project and new class "App2" to see if you can replicate the issue with that same version of NetBeans.
If you cannot then review why App compiles and App2 does not.
If you can replicate the problem then download the most recently nightly build to see if you can still replicate the problem (i.e. Invalid source code compiles cleanly). If you cannot then I don't think it is worth raising a bug report or spending further time on the matter.
However, if you can replicate the problem then by all means raise a bug report. But I strongly recommend being able to replicate the failure before doing that. Otherwise you are likely to get a WORKSFORME response if the NetBeans team cannot replicate the issue.
One more thing: it would be helpful to update your OP with the stack trace for that RuntimeException, which you should also include in your bug report.

Ah...I see it now. At some point of time I checked the "Always run without asking" checkbox and since then my IDE is ignoring all the compile time errors without any warnings.
Sorry guys...my bad.

Could not load JIntellitype.dll from local file system or from inside JAR

I am trying to use JIntellitype to listen to global hotkeys but I get this error:
Exception in thread "main"

I have loaded the jar file and I also pointed to the folder where the dlls are located through Referenced Libraries.
Here is the code I am trying to run:
import com.melloware.jintellitype.HotkeyListener;
import com.melloware.jintellitype.IntellitypeListener;
import com.melloware.jintellitype.JIntellitype;
public class HotKey extends Thread implements HotkeyListener, IntellitypeListener {
private final int CTRL_C_SHIFT = 10;
public HotKey()
{
JIntellitype.getInstance().unregisterHotKey(CTRL_C_SHIFT);
JIntellitype.getInstance().registerHotKey(CTRL_C_SHIFT, JIntellitype.MOD_CONTROL + (int)'C', JIntellitype.MOD_SHIFT);
if (!JIntellitype.isJIntellitypeSupported())
{
System.exit(1);
}
}
#Override
public void onIntellitype(int arg0)
{
}
#Override
public void onHotKey(int key)
{
if (key == CTRL_C_SHIFT)
{
System.out.println("smg");
}
}
}
Any idea how to fix this?

Your problem will occur because of a version problem between that OS version and the JRE version.
You should check:
Whether an appropriate dll file is installed in your OS system folder.
JIntellitype package has two dll files, one is for 32bit OSs and the other is for 64bit OSs, they have different names.
Check your Java Platform version in the properties of the projects.
You can try to change the Java Platform, if there are more than one types of JDKs.
Make sure about which one is for 64bit or 32bit version.
Have good luck!

I recommend you do something like this:
try
{
JIntellitype.getInstance().unregisterHotKey(CTRL_C_SHIFT);
MyHotKeyListener hotKeyListener = new MyHotKeyListener();
hotKeyListener.addObserver(new MyEventListener());
JIntellitype.getInstance().addHotKeyListener(hotKeyListener);
JIntellitype.getInstance().registerHotKey(CTRL_C_SHIFT, JIntellitype.MOD_CONTROL + (int)'C', JIntellitype.MOD_SHIFT);
}
catch (JIntellitypeException je)
{
logger.warn("JIntellitype initialization failed.");
// DO WHATEVER (NOTIFY USERS?)
}
I can point to other threads, including one where the creator of this library himself denies problems with the library. However, many users such as myself encounter these sort of problems from time to time where JIntellitype fails to initialize and the only solution is to reboot the computer. Because of this, you should catch the JIntellitype exception (the only exception thrown by the library) and warn users (via dialog window) that the hotkey failed to register. You should give them the option to continue without them, or to reboot the computer and trying again.
Trust me.... unless this is a constant problem (which means you configured it incorrectly), it is your best alternative. This WILL happen from time to time at random.

java.lang.NoSuchMethodError - Ljava/lang/String;)Ljava/lang/String;

My code is giving an error below;
Exception in thread "main" java.lang.NoSuchMethodError:
com/myApp/Client.cypherCBC(Ljava/lang/String;)Ljava/lang/String;
But it's working fine in an another local environment. My code so far is below;
try {
System.out.println("Encrypted CBC passwd : "
+ Client.cypherCBC("CypherThePassword"));
} catch (Exception e) {
e.printStackTrace();
}

This is due to a run-time JAR or class mismatch. the "Client" class which was there at the time you compile your application has a static method "cypherCBC" which gets String parameter, but at run-time class loader has loaded the "Client" class which doesn't have that kind of method (same name with same signature).
if you can debug the application at runtime, put a break-point at the line which exception was thrown, then try to evaluate following expression,
Client.class.getResource("Client.class")
, then you can find where the class has been leaded from, then you can decompile and try to troubleshoot the issue.

I got the same error while running a web application in Weblogic.
The reason for this error is there are two versions of classes are in the environment.To fix this you have to figure out which .class is using at the run time.
I used following to identify which class is loaded at run time.
-verbose:class

There is a duplicate class on your classpath.
So, That is why JVM is getting confused that which one needs to pick because both classes have a same method with a different signature that you are trying to call.

UnsatisfiedLinkError, despite setting Djava.library.path variable

I am trying to integrate IBM's CPLEX library with my java application. For now, i'm just trying to create an IloCplex object. I added Cplex.jar, and it compiles fine, but when I run this:
public class cplexTest{
public static void main(String[] args){
try{
IloCplex cplex = new IloCplex();
}catch (Exception e){
e.printStackTrace();
}
}
Cplex prints this message before throwing an exception:
java.lang.UnsatisfiedLinkError: no cplex124 in java.library.path
java.library.path must point to the directory containing the CPLEX shared library
try invoking java with java -Djava.library.path=...
I pass this argument to the JVM: -Djava.library.path="C:\Program Files\IBM\ILOG\CPLEX_Studio124\cplex\bin\x64_win64. This is the location of cplex124.dll. Every tutorial i've seen gives the same steps, and i feel like i followed them pretty well.
What am I doing wrong??

What I've found in the interwebs is that one possible cause for this problem is the dll being in 32 or 64 bits and your java being in the opposite architecture.
Try verifying that your java and cplex.dll match.
