Description Chris Grey

Build Identifier: 20090920-1017

I have a VERY simple project, that's actually just the beginning of a project and I'm having trouble getting Eclipse to debug the little bit I've got going so far. Eclipse doesn't complain about any syntax errors. And it appears to be compiling the *.java files into *.class files just fine. It just won't debug the files without throwing an error when my code goes to create an object. 

In the error message, there's a button that says "Edit Source Lookup Path...". When I click that, it shows me the default folder structure Eclipse is using. It looks correct and my files should be part of the default collection of directories. If I manually add the source location, it doesn't help. I still get the problem. 

Reproducible: Always

Steps to Reproduce:
1. Extract out the attached Zipfile. The folder structure is my workspace and project folder. So you can open the "Projects" folder as a workspace (zip includes the Eclipse .metadata folder). From there, you should see the "Simulator" project.

2. Jump to the debug view and set a breakpoint at the beginning of the program (main). 

3. When I get to line 30 in the debug, I get the error.

This is my workspace folder and project including .metadata folders. Hopefully this will reproduce exactly what I'm seeing for others

Can you attach a screen shot of the problem?

The problem...

This is not an error with the debugger. It looks like you don't have source for the system library class you are in (i.e. the constructor of 'ClassNotFoundException'). Usually when a 'ClassNotFoundException' is thrown you end up at the throws clause (i.e. suspend on uncaught exceptions) - so I'm not sure why it suspended in the constructor of the exception - the thread text just says "suspended".

This does not look a debugger problem - looks like your runtime claspath is missing a class (binByte).

If you open "ClassNotFoundException" in and editor (using the "Open Type" action), do you see source?

That's what I would've thought that meant. But the binByte.java class is right there along with the disassembler.java file. Refer to the screencapture I've included. Pull down the spanned Zipfile and open it up. You should see the file structure exactly as it exists on my machine. Open the Projects folder as your workspace, and inside you should see the Simulator project.

Have you been able to reproduce this with my files?

No - what utility are you using to split to zips? what should one use to put them back together?

I used Winzip to span them. I've never tried, but I would think that 7-Zip could extract a spanned/split zip archive.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
