Asankha C. Perera commented on SYNAPSE-168:
-------------------------------------------
The problem is that JBoss returns an error message in HTML targeted for a
browser, when a Web service encounters a fault or is unavailable. The typical
response expected by Synapse in such a scenario is a SOAP fault. We may be able
to address this issue as an enhancement over our typical behavior - but this
would take some investigation.
I do not understand what you mean by JBoss running out of memory? As I
understand Synapse runs on a separate host than JBoss? but do you mean that if
JBoss responds with a HTTP 500 without a body, Synapse encounters an exception?
If so the same enhancement I propose could address this issue as well
