Opened CronTabTest from Jenkins sources. Had bogus error messages in it (should have found generated sources); and this exception was thrown.

Havebn't touched the editor for 10 secs or so and got this.  I have recently upgraded from 7.3 to 201303232300 with imported settings and have only 3 files open.

This is thrown constantly in the current dev builds; should be considered P2.

Nothing special.

Tempted to mark this P1 since it renders the IDE close to useless.

Fixed in jet-main.

Interestingly we've been seeing the same issue (or very similar) in ENSIME https://github.com/ensime/ensime-server/pull/1764

which can be reproduced by trying to typecheck these snippets (remove our @ syntax for cursor location) in any OpenJDK8 (Windows and OSX seem to throw StackOverflow rather than NullPointerException)

a related issue (doesn't throw in Windows and OSX is)

I noticed that the fix is in http://hg.netbeans.org/main/nb-javac/rev/2b9b60de0c69 which appears to be the SUN javac API.

But this fix hasn't made it back to the OpenJDK mainline, for some years. Will that eventually happen?

I don't think we want to start using the Netbeans tools.jar but if we did, where is it published?
