I20050414-1107 Sun JDK 1.5.0-b64 Tried using content assist in the Display view (while debugging). Didn't work, got the following exception. Sorry, don't know how to reproduce.

I cannot reproduce the bug. The stacktrace suggest a test case like ...foo.foo(...,foo<<complete here>>,...)... Added protection to avoid AIOBE. Now the completion will work but without an expected type to compute relevance.
Verified in I20050510-0010 + JDT/Core v_556. Protection code is in.
