Description

The process in question has the following structure:

receive init message
reply
flow
while true
receive get message
reply
while true
receive getAndIncrement message
reply
increment variable
receive close
exit

(Python-style indenting for nesting, and sequential activities are on successive lines.)

The resulting exception is:

Caused by: org.apache.ode.bpel.iapi.BpelEngineException: Engine requested response while the message exchange hqejbhcnphr2achs6i6uh5 was in the state RESPONSE

With a debugger attached, if the initialize operation is called, then the response is returned, but getAndIncrement is the operation listed in the underlying mex in the call to BpelRuntimeContextImpl::getMyRequest, and this request does exist yet.

I have the feeling that the implementation is not properly hashing port type/operation pairs but rather just port types?
