Thanks in advance.

Seeing a class ObjectLiteralField in the stack trace which doesn't even exist any more in today's sources, and considering that this was observed in Eclipse 3.5.0 while we're developing 3.8 I'm afraid we may not be able to do much. It's rather unlikely that we'll be able to reproduce this problem in any recent version. I don't even remember seeing that class. Nor could I find any bug report referring to that class. Leonardo, if 3.5.0 doesn't work for you, the best resolution would be if you upgrade to a newer version of Eclipse, if possible. If you must use 3.5.x, maybe even an upgrade to 3.5.2 will fix the issue? Hi. I will try to use 3.5.2 release of Eclipse. I will inform You if issue will be fixed or no. Thaks by now. Best Regards, leonardo. Is 3.5.2 an upgrade fo 3.5.0 or new version? 3.5.2 is second maintenance release for 3.5. If you are unconstrained by other considerations, you should upgrade to 3.7.1 which is most recent official release. Can I migrate to 3.5.2. directly from Eclipse (using help -> check for updates)? Hi. If it can be useful, Eclipse has just closed unexpectedly with this log: **********************************************************************start-log !ENTRY org.eclipse.core.resources 2 10035

Sorry, I did not understand your suggestion. (In reply to comment #10) > Sorry, I did not understand your suggestion. I moved the bug to a different component where the problem seems to be. This wasn't directed towards you. Thanks for the stacktrace. > I moved the bug to a different component where the problem seems to be.
Mmmh, no. The initial bug report is not for JDT (Core or UI) but JSDT. Moving there as the NPE in
AppearanceAwareLabelProvider.evaluateTextFlags(AppearanceAwareLabelProvider.java:121)
looks like coming from a messed up install: neither the 3.5 nor the 3.5.2 code can throw an NPE at that line.
I suggest to do a fresh 3.7.1 install.
