In my composite app I have ComponentA which has a reference to ComponentB. I'm
seeing an intermittent issue where ComponentA tries to invoke a method from
ComponentB and an UndeclaredThrowableException is thrown. This isn't using an
official release (its 1.5.1 SNAPSHOT r810694) so this may have already been
fixed. Here is the stack trace:
