Are you able to reproduce the issue? If so, is the issue reproducible even with
clean caches (deleted var/cache subdir of your userdir)? Thanks.
Comment 3 lolo_101 2010-05-04 20:00:28 UTC 
Yes, this issue is systematic with this particuliar project. Event after deleting the entire cache directory and restarting NB.
Comment 4 Dusan Balek 2010-05-05 12:08:47 UTC 
Great! 

Could you please try to clean your caches again, run NB with the patched javac (containing an additional logging), and attach then the messages.log file to this issue?

I will add the patched javac-impl.jar. You need to replace the netbeans/java/modules/ext/javac-impl-nb-7.0-b07.jar by it (it should be named javac-impl-nb-7.0-b07.jar)

cp javac-impl.jar netbeans/java/modules/ext/javac-impl-nb-7.0-b07.jar

Comment 6 lolo_101 2010-05-18 12:29:15 UTC 
Hi Dusan Balek,

I patched my NB with your javac-impl.jar and the issue did not reproduce !
In addition, the project now runs fine !

Before that, one of the classes under the "build/classes" directory was deleted when I hit the "run" button and was replaced by a file with the same name but a ".rs" extension... Then the project obviously failed to run with a "ClassNotFoundException".

I couldn't find the messages.log, I guess it's because no exception rose this time. However I hope these clues will help to discover what was wrong.

Best regards
