Jan Hoskens commented on RCP-526:
---------------------------------

I just replaced our simpleApplicationPage with the TabbedApplicationPage and it seems to work fine. When looking at your  trace, I do notice the usage of glazedlists that is trying to grab a lock. Maybe the issue is situated there? Did you try a simple setup as well (no glazedlist)? If it still persists, can you attach an example which leads to this lockup?

> I'm seeing my application lock up randomly during startup.  I'm using the TabbedApplicationPage, and after getting a stack trace I can see that its locking during the call to DefaultApplicationWindow.setActivePage.  I see this occur from the command line, in the Eclipse IDE and as a Java Web Start download.  I'm using Java 1.6_03 and I see this occur in all three environments (command line, Eclipse 3.3, and Java Web Start).  Any idea what may be causing this?
