There is something odd going on here, possibly two separate bugs. I was going to confirm that it is not so much the log files as the informational box about them that is causing the crash (as per Michael Plump's comment https://bugs.launchpad.net/ubuntu/+source/azureus/+bug/68020/comments/3). Using Azureus 2.5 and Java 1.5 switching to GCJ solves the problem. Once the message has been acknowledged using GCJ, one can switch back to Sun Java even if the logs directory is not empty.
However, renaming/removing the logs directory does also fix the problem (i.e. no need to switch to GCJ for one startup), but without displaying the message about not shutting down properly. Azureus has recreated the logs directory, debug_1.log and the save subdirectory. If I "killall java" now, Azureus still starts up properly the next time under Sun Java but *never* displays the message about not shutting down properly. My "save" subdirectory used to have things (copies of logs?) in, but now has nothing... I can't see why it works now but doesn't recognise that it failed to shut down properly (so I can't recreate anymore!). -- Azureus 2.5.0.0 crashes https://launchpad.net/bugs/68020 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
