We've been struggling here at the office with a seemingly unsolvable bug in one of our (massive) applets, this one being a Java simulation of MS Word, for exam purposes. The exception seems to stem from swing itself, and I'm not sure how I would go about solving it. Here's what happens:
The applet loads with a loading screen till 100%. After this, the components are all displayed in a broken way as if some of their paint methods are not being called correctly, hovering the cursor over some buttons etc. does make them flash/display for a while. And an exception is printed to the console every second or so. (See below) This bug does NOT occur within Eclipse, only in the browser.
Summary: Applet components all get built without exceptions, but on every "paint" call of a some component (I assume), it visually bugs out and the following is printed every second:

Help would be greatly appreciated, as this is driving me nuts, I can't seem to find what triggers this, as the code is from a previous developer, and an utter mess. I have tried different JDK versions.
Thanx.
java.lang.ClassCastException: javax.swing.JLabel cannot be cast to
javax.swing.text.JTextComponent
see components tree for JTextComponents, there isn't JLabel, JLabel isn't member of JTextComponents
safest could be to test if (Xxx instanceof JTextComponent) before any casting
Found a fix to my problem. The target Java version was wrong. In the build.xml file, there were the following lines:
<property name="target" value="1.5" />
<property name="source" value="1.5" />
Changed those to 1.7, and voila! This seems to have been a Swing bug that has been fixed in the newer versions of Java.
I've noticed that this problem can occur when a JLabel with tags around the content contains nested tags. The solution is to escape the angle brackets on the

What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 3 years ago.
I'm currently getting these errors, I've tried doing a few things to see if that would help. I even used the debugger to find out why these errors are occurring, but i'm still not sure.
If anyone would be able to help it would be really appreciated.
I tried looking at the suggested post and i made the fixes suggested, however this didn't help, the errors still remain the same.

NullPointerException throws when the object where you try to call some method does not exists. So we have it at c3537779.ByteReader.getBytes(ByteReader.java:14) and you need to debug the process on 14 row of class ByteReader and look what it calls. If You will see something like myName.myMethod(); you should check creation process of myName object because it null.
Hi,
I'm trying to execute a jar file, overwriting some java originals interfaces to connect with the database, changing the method setBoolean to receive an object like parameter.
That's the original interface method:
void setBoolean(int parameterIndex, boolean x) throws SQLException;
That's my change:
void setBoolean(int parameterIndex, Boolean x) throws SQLException;
My changes were made at interface java.sql.PreparedStatement. For my changes to be called, when I start the application I'm using the command:
java -verbose:class -Xbootclasspath/p:C:/Users/user/Desktop/myproject/src/main/java -jar safepdv.jar
With the command "-verbose:class" I can verify that the class with my changes are being loaded.
However, when the method setBoolean is called by the application, he isn't founded, and my return is:
Exception in thread "AWT-EventQueue-0" [Loaded java.lang.Throwable$WrappedPrintStream from C:\Program Files\Java\jre1.8.0_91\lib\rt.jar]

How can I make my method was really called instead of the original method?
The calling code is still trying to pass a null value to the old method's signature (which expects a boolean, and not a Boolean). You would need to recompile the calling code so that it binds to the new method signature: the method signatures to be called are fixed at compile-time.
Also, note that PreparedStatement is an interface - changing its definition is likely to break all classes implementing said interface. Most notably, each JDBC driver will include its own implementation; you would have to recompile the drivers from source to fix this.
It is possible, but ugly and unmaintainable, to decompile the calling code and simply fix it at the point where the null is being passed, and then recompile it. You can automate this to a certain point (think bytecode-editing libraries), but the gist is that not having access to the source code making the bad calls is a severe drawback.
I need your help.

How can i fix this error?
Thanks in advance.
Mr_SoUndso
PS: I know a similar question was asked before, but without stack trace. There also was no answer given.
A friend showed me how to fix it:
You need to make your library available in your jar.
Then everything is working fine
Assuming you are exporting the app as a jar file, you need to provide the path of that driver jar while running the app, e.g.:
java -cp '<path_to_driver_jar>' yourApp.jar
This would make sure the library is available to your app and it will work fine.
I've been having lots of trouble trying to create a file ANYWHERE in any directories and I've had no luck.
#SuppressWarnings("resource") //Install the modpack and create files
public void installModpack(){
File f = new File("\\ultima");
f.mkdirs();

The stacktrace does not match the code in your question. The stacktrace says that installModpack is calling File.createNewFile, but in your code there is no such call.
The exception message seems to be saying that it is trying to create "C:\Users\Drew\AppData\Roaming", or create a file in that directory. That doesn't match the pathname "\ultima" that you are apparently trying to use.
Without seeing the actual code, we can't tell you what the real solution is, but I would:
Check to see if that "C:\Users\Drew\AppData\Roaming" exists using some other tool.
Examine the sourcecode and/or run your code using a debugger to figure out which installModpack method you are really using.
I answered this myself. Some code I had later in the code messed with this :p
The correct usage for anybody who is looking here is:
File f = new File(System.getenv("APPDATA") + "/.ultima");
f.mkdirs();
I have a peculiar situation here in an application I've programmed using a Substance LookAndFeel. In my application, as seen in the screenshot below, I have three JMenus in the MenuBar.
The one all the way on the right (Take Screenshot) is click-able and takes a screenshot of the entire application window. It has no MenuItems beneath it and works as a standalone faux "button".
Upon being clicked, it works perfectly fine. But in the console I get a HUGE block of errors related to what I'm assuming is the current L&F I'm using (seeing as this didn't happen with the System Default L&F).
Another question I would like to have answered is how to fix the opaque part of the menu's shadow, also as seen in the screenshot provided. None of this affects execution of the application in any way, I would just like them both resolved to ensure execution is optimal.
If any of my code needs to be posted to help resolve the issue, please recommend where you think thr issue is originating from (i.e. the Robot, or the L&F, or the MenuBar, or whatever). I will post whatever is needed.
edit: I have done some more exploration and it seems to occur only when any of the Menus are selected, then I hover over to the Screenshot menu. My guess is simply because it has no MenuItems to be displayed, but I could be wrong. I still haven't a clue on how to resolve the issue, though.

This is a bug in Substance that is based on older code in JGoodies. Kirill took an older snapshot of ShadowPopup that didn't have code to check for things like zero width or height. Current versions of ShadowPopup look for that error and handle it properly.
Substance itself is no longer maintained by Kirill, but I do have a maintenence fork. Could you post this as an issue there?
