Hi I have similar problem. During invocation of function 
JTabbedPane.setSelectedIndex my application hangs.

Here is part of stack trace from jconsole:

Last thread is causing the deadlock, but I don't know why. Currently I use 
some components built on SWT (3.5 Milestone 1). Also I cannot notice any 
swt function invocations in the whole jconsole trace.

I will be very grateful for reply. What do you think?
