Reproducible: Always Steps to Reproduce: 1. Perform a java search or refactor like rename a var. 2. Internal error occurs with the above stack trace I tried shutting down eclipse, removing all .index files from the .metadata/.plugins/org.eclipse.jdt.core directory and restarting eclipse. It rebuilt all the indexes but the exceptions still occur.
Satyam, please take a look and see if this needs to go in for 3.6.1 and set target suitably -- Thanks.
Kelly, Is there a way I can reproduce the problem?
Kelly, Can you make sure of the build-id? CategoryTable doesn't exist any more. It used to exist before 7th May.
Probably a different jdt.core plugin is getting used. Can you please verify?
(In reply to comment #4) > Probably a different jdt.core plugin is getting used. Can you please verify? Sorry for the erroneous bug report. We built the jdt.core from a git cloned copy of the cvs repository, but somehow the commit which removed this file somehow got skipped.
FYI, the official Eclipse git repositories listed at http://dev.eclipse.org/git/index.html have the same issue.
(In reply to comment #6) > FYI, the official Eclipse git repositories listed at > http://dev.eclipse.org/git/index.html have the same issue. The official git repository has CategoryTable.java but it is no longer being used. Hence, if you just delete this file, that should be good enough. I have raised the bug 322885 for this issue.
