StackOverflow error in tree viewer [message #436851]

I have a tree view that is displaying messages received from a server
that my Eclipse application is talking to. At times there can be quite
a number (>1000) messages revceived within a few minutes. At times, my
users have gotten stack overflow errors. These seem to be quite random
and I can not find a pattern other than the trace that is generated is
the same. The top of the traceback is:

!MESSAGE Unhandled exception caught in event loop.
!ENTRY org.eclipse.ui 4 0 May 25, 2004 13:30:28.52
!MESSAGE java.lang.StackOverflowError
!STACK 0
java.lang.StackOverflowError

The communication is happening in another thread and the view gets the
updates via a property change event being fired. The fireProperty
method is using Display.asyncExec() to notify all the listeners for the
property change.

I am at a loss as to what could be causing this. Any help would be
greatly appreciated.

Thanks,
Phil
