I have a problem with debug mode, uninstalling-reinstalling eclipse/JDK have not solved it.
The program runs just fine on it's own. but eclipse throws errors at me whenever it enters a new class in debug mode.
Better just to show you.
http://www.youtube.com/watch?v=2KBGUApHpg0
If I put the break point at a later point after it has entered a class, it continues the debug just fine. If I keep step into(f5) it works through the error messages, continues with the program, gives me some more errors when it return to the parent class and finish the program correctly.
I don't know when it started doing that, I didn't use eclipse during summer.
Any answers would be helpful, the solutions I have tried from the net have all failed me.
If someone is interested, I can pm a ip and password for VNC session
public class TestPrintALine {
public static void main(String[] args) {
PrintALine test = new PrintALine("Hello");
System.out.println("Done");
}
}
public class PrintALine {
public PrintALine(String line) {
System.out.println(line);
}
}

My guess is that you have an exception breakpoint set. Class loading can
throw ClassNotFound/NoSuchClass that child class loaders handle when the
exception is thrown by a parent class loader. The child loader uses its
lookup path after the parent failure. The class is found and you
program completes normally. This isn't a bug, it is just how the
process works.
In the breakpoint view, there is a tab (or tool button) to show
exception breakpoints, check there to see what you might have set.

Generally you're asking the debugger to step into the logic from the
current point at which you've stopped. The first time you try to use a
class, it loads, and you end up stepping into the logic for loading it.
I've not seen the particular exception you've shown (it looks like an
exception breakpoint but I didn't see one in your list of exceptions)
but I often end up stepping into class loader logic. I just tell it to
*step out* and do another step into. In the video you do lots more
*step into*.

Not sure what you mean by these messages? Note the suggestion was that
you already have an exception breakpoint and should remove it. (But I
didn't see one in your video.)

Feritz,
If you tell it to continue, does it continue and run the application
further or does the application terminate completely? You removed all
breakpoints by clearing the breakpoints view?

i have class file in jar com.t.framework.batch.JobController , this class is entered in Main Class entry text box
arguments are as follows
program arguments
jobdefinition/archiveExtractor.jdef FORCE_FROM_STEP01
vm arguments
-DAPP_HOME=C:\Documents and Settings\x12\t855_vox_3.0_dev\vobs\vox_source\vox
-DDATA_HOME=C:\Documents and Settings\x12\t855_vox_3.0_dev\vobs\vox_source\vox
-DENV=local
-DLEVEL1_SHORTNAME="vx"
-DLEVEL2_SHORTNAME="ae"
i emptied breakpoints in break point view
i can run hello world class file with main class, getting result too..
sometimes it get terminated
but when i run using the option debug configuration
it throews the following error , i m not able to do debugging further, but not getting terminated. i have to terminate it manually.

Feritz,
I think this is influenced by Window->Preferences->Java->Debug, i.e.,
Suspend Execution on uncaught exception.
