henrik lindberg commented on JBSEAM-1689:
-----------------------------------------

Sorry about not providing more information Gavin, I should have said that the problem is intermittent.
Was hoping that posting the stack trace was of help, and that it gave enough information. 
Will post more info if I find out more about this problem.

Sorry for wasting your time, if info is not useful.
Cheers.
