20080427-2000 Linux GTK, Open Client 2.1 Accessibility testing (screenreader on) VM crash occurred when opening the new class wizard. Can't reproduce. Not sure if its a problem in the screen reader, or SWT. Feel free to close if the information is not helpful enough.

Created attachment 154566 [details] Log of Eclipse crash in libgail.so if Assistive Technologies are enabled
I'm not sure if there is any relationship, but I can not finish the eclipse if the assistive technologies are enabled. After I close eclipse, I need to kill eclipse and java.
Actually I am running version 3.6 M4 and everytime I close eclipse eclipse doesn't finish. Also the VM doesn't finish too. I need to kill both, eclipse end java. The same happens with eclipse 3.5 and 3.4.
I am not going to be able to look at this until January. I have set the target milestone to 3.6.

Maybe it fixes this problem as well. It is hard to tell since there is no steps to reproduce this one.
We will look again at these crashes and hangs for 3.7, however if anyone has any steps to repeat in 3.6, then please list them here. Regarding the hang on exit mentioned in comment 4 and comment 5, this hang does not happen if an IBM Java VM is used, so there is some interaction somewhere in the Sun Java VM shutdown sequence. I read that a VM can hang if System.exit() is called from a shutdown hook, so that might be one thing we look for. (They are supposed to call Runtime.halt() from a shutdown hook. I don't know if or how many shutdown hooks Eclipse has). http://dtm.livejournal.com/29433.html http://codeidol.com/java/java-concurrency/Cancellation-and-Shutdown/JVM-Shutdown/
Jose, I saw your comment on the Orca list that you no longer have the Sun JVM hanging on exit when you use Eclipse 3.7 on Ubuntu 11.10 and Ubuntu 12.04. Which Sun VM version are you using?

Eclipse a117 under linux have changed significantly and I can't reproduce this issue. Please reopen if you can reproduce it with latest SWT.
