Description Edoardo Comar CLA 2005-05-23 11:01:44 EDT 
I get this exception either when performing a caller hierarchy or when
performing a workspace reference search.
result is: I can't find what I am searching for ;)

Error 2005-05-23 15:49:09.776 An internal error occurred during: "Java Search".

the source code is a very heavily overloaded static method used all over in our
plugins ....

Occurred on N20050523.
Comment 2 Jerome Lanneluc CLA 2005-05-24 02:05:35 EDT 
Steps to reproduce this problem would be most welcome.
Comment 3 Edoardo Comar CLA 2005-05-24 04:46:42 EDT 
Jerome, there are no particular steps.
I just performed a call hierarchy serach and since it failed a java search for
reference in the workspace.
in both cases with the cursor over a method in one of my plugins.
I can't send our entire workspace unfortunately.

I even restarted eclipse and rebuilt from clean - same result.
I then ran M6 and the serach completed successfully.

FYI here is a screenshot of the outline of the class the searched method is
highlighted
