Description Tony Tsui 2006-01-23 02:42:50 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20051215 Epiphany/1.9.5.1

Description of problem:
Doing Word Completion, via the shortcut Alt+/, in the text editor results in a error dialog appearing with the following message:

"Word Completion" did not complete normally. Please see the log for more information.

Reason:
java.lang.NullPointerException

Clicking on the Details button only shows "java.lang.NullPointerException" in the text box.

Doing Word Completion via the Edit menu doesn't do anything, i.e. word is not completed, although there is no error dialog.

This happens in the editor for Java, C and Python files.

Version-Release number of selected component (if applicable):
eclipse-platform-3.1.1-1jpp_15fc

How reproducible:
Always

Steps to Reproduce:
1. Type a few characters of an existing word
2. Press Alt+/ OR Go to Edit->Word Completion

Actual Results:  Alt+/ produces and error dialog.
Edit->Word Completion doesn't do anything

Expected Results:  The word is completed.

This is a class library issue.  I'll add a reference to the upstream bug.

Comment 3 Tom Tromey 2006-02-13 22:58:34 UTC

I checked in the regex fix to the gcc 4.1 branch.

Thanks.  This works for me now with gcc-4.1.0-0.27.
