The AJDT builder hangs periodically on me, e.g., on projects that are in another workspace. Worse yet, I find that it's basically impossible to stop it: if you select stop on the builder, the thread still runs, and if you try to exit it won't exit. If you try to, e.g., edit files or turn off automatic compilation, that also invokes the builder. In addition to preventing hanging in the builder, it would be good to make sure that if things hang, you can kill it and you can reconfigure without reinvoking. One thing that does work around the issue is turning off automatic builds, force quitting, then restarting & editing (phew). I will also include some error log entries I saw at hang time... (see attached
Created attachment 25080 [details] example of hanging AJDT builder... even on exit this is with the 19+20-jul-05 dev release

I can't be sure it's the same problem, but we managed to consistently reproduce a hang with a particular workspace here, and tracked it down to a deadlock involving updates to the editor's title image. This is fixed in the following builds: AJDT 1.2.1: BUILD COMPLETE - build.536 Date of build: 09/30/2005 17:55:44 Time to build: 43 minutes 29 seconds AJDT 1.3.0: BUILD COMPLETE - build.130 Date of build: 09/30/2005 17:18:37 Time to build: 32 minutes 45 seconds If you see another hang as of these builds, please reopen or open a new bug.
