Comment 1 Dani Megert

Are you sure that you have 3.6.2 installed (you should have 'org.eclipse.jdt.core_3.6.2.v_A76_R36x.jar' in the 'plugins' folder)? We fixed bug 329288 for 3.6.2 which looks related to your issue.

Which JRE are you using?
Do you have source and/or Javadoc attached?
If Javadoc is attached: is it on disk or fetched from the web?

Should be a dup of bug 329288.
