This is a problem on Mac OS X 10.5.2, using a Win2K server as the location of the files. I'm using JVM 1.6.0 in the project. There is an inner class- NvestorPanel.class, which if I remove into it's own class the error goes away.

Changing component from 'APT' to 'Core', as I don't believe this has anything to do with APT.
It looks like a VM problem: it returns "Unknown error: -37". After shutting down, rebooting your machine, and restarting Eclipse, can you still reproduce?
Yes, I can reproduce after rebooting.
So what happens if you rename the inner class to 'X' ? Or you remove all of its method bodies ? Or you add another inner class named 'NvestorPanel2' ? Do you have any other builders attached to the project ? Or any ant scripts that may be writing .class files to the output folder ?
That worked (renaming it to X). It seems that any name longer than 10 characters causes the problem to occur. If I name the inner class 10 characters or less, the problem disappears! Thanks for the suggestion. By the way, I just installed Mac OS X 10.5.3 and the problem persists. It must be something on the Win2K server, but that is fully up to date on patches as well.
Ok - I expect the filesystem is enforcing some filename length baloney. Can you also try to define a top level type in the same package named: 'InvestorApplet_NvestorPanel' that should result in a class file with the same length for the name as the inner class. thx
This appears to be a filesystem issue with the length of the name.
Verified for 3.5M1 using I20080805-1307
