I'm also having problems with foreground thread pauses when using JBoss Tools. It would appear that the entire Eclipse hangs when for instance moving the Project Explorer with the cursor keys, passing by the "JBoss 6.0 Runtime" classpath element. There is no discernible Task going on in the Progress View, since the SWT thread is stuck.

I tried it in a debugger, and got this:

Looks like some expensive classpath code was unexpectedly called from the UI thread. This is on Helios SR1 with JBoss Tools H28 Beta 2.

Keep up the good work - in general ;-)
