I am running Helios JEE SR2, with a Tomcat Server.

When I start the server in debug mode, I continue to get some of my threads being suspended for no apparent reason.

I have attached a screenshot that shows this. AFAIK I don't have any breakpoints set, so I don't know what would be causing this.

Can you confirm there are no breakpoints set (using the breakpoints view)? From the screenshot it says you are suspended on a RuntimeException, so you probably have an exception breakpoint set.

There are no Exception breakpoints set.

I should add that I am hitting this suspension, as part of the thread dying. I think that Tomcat triggers a runtime exception, to effectively kill the thread. If I start single stepping the thread I end up in an uncaught exception handler.

I should also add that this happens on both the SUN and the IBM JVMs.

How about option on the Java > Debug preference page -> Suspend execution on uncaught exceptions, it it enabled?

Ah, I didn't see the Java > Debug preference page

instead I was looking on the Run/Debug set of pages :-( 

Thanks for pointing that out.

Closing as invalid ... although it would great if someone could think of a way to make this more user friendly.
