Build 20020129 1. Search for declarations of a java method. 2. Select one of the results and asked for references. Internal error. Log below. 3. Rebuild All, try again, still get internal error. I zipped up the workspace if you want me to upload it somewhere. Steps to recreate in the workspace as follows: 1. Open WS. Search --> Java --> method --> requestActivation --> declarations 2. Select the first match in the Search List --> References --> Workspace.

the NPE happens in JDT core.
Moved the initialization of the matching openables set before initializing the polymorphic search as this can cause some potential matches to be found. Verified this is fixed with Lynne's workspace.
