Re: Corrupted Java development environment

Hi David,

The good news is that there is an open Eclipse bug for this problem: 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=161021  The bad news is 
that, judging from the bug report, the developers haven't been able to 
isolate and fix the bug.  So you may want to append your scenario to this 
report.

Some background and hopefully a workaround fix:

All global preference settings are stored in properties files in the 
directory: workspace\.metadata\.plugins\org.eclipse.core.runtime\.settings 
 

The file that stores the Java compiler preferences is: 
org.eclipse.jdt.core.prefs

And the specific setting related to the NullPointerException you are 
getting is: org.eclipse.jdt.core.compiler.maxProblemPerUnit=10

If you get the error again, shutdown WDSC and take a look at this 
preference.  It should have a numeric value.  If it does and the problem 
persists, then try to compare (or just replace) the 
org.eclipse.jdt.core.prefs file with one from a different workspace.

Um, color me confused ... this time I was able to get it to work by
restarting WDSC.

This kind of thing drives me crazy.
