Hi Kohsuke,
This of course shouldn't come as a surprise, but you were spot on. I
was foolishly assuming that the problem must be related to my code,
rather than our framework code which in this case was adding a
WS-Addressing To header with a null value. I haven't tried the latest
code, but take your word for it that you've changed it to throw a more
meaningful exception. In the meantime I'll fix my code (o:
cheers
