Scala IDE plugin causes hangs even for normal java projects

I have been having some hangs in Eclipse and have tracked them down to the Scala IDE project. When the IDE hangs I have run jstack and got the following output. I am not actively using Scala in my workspace (that I know of), but it still shows up in jstack

This issue will not be fixed in master.
There is partial fixe in the wip_exp_backport branch. Can you give it a try ?

Thanks for the fix, I am unlikely to have a chance to test as its a work computer and we have a standardised eclipse installed. As well, I would rather not spend the time building this plugin, as I am not an active user of the Scala IDE at work, I was just getting hit by it being included in the standardised eclipse.

Sorry! I hope the stacktrace gave you enough to go on.

wip_exp_backport is available like "master" branch from download page (not need to compile)
update-site : http://download.scala-ide.org/nightly-update-wip-exp-backport-2.8.1.final

This version is the future "release".

Hi, I'm having the same problem and it looks like GDT guys too. See:
http://groups.google.com/group/google-web-toolkit-contributors/browse_thread/thread/668646e64f4b4d1d/8ca678559fa8281d?#8ca678559fa8281d
My scala-ide version is 2.0.0.201105131126-beta4-92f1b27, but I had this issue with all versions I tried in the past.
I use Eclipse Java EE IDE for Web Developer Helios Service Release 2 with bunch of additional plugins, including Spring IDE, Hibernate Tools, FindBugs etc.
Any idea when this could be fixed?

Thanks,
Marek
