Hi Dan,
I am afraid I have much shallower knowledge of the CXF code than
Alessio so I hope you will forgive me asking a rather simple-minded
question. Could you explain why CXF needs to perform correlation of
outgoing requests and incoming responses?
regards,
Andrew Dinn

Hmm..... I wonder if we can tackle some of these things kind of piece
meal, in steps:
1) Scenario one is a single Bus, but multiple MAPCodec's. This should
be fairly easy. If the MAPCodec stores it's storage map as a property
on the Bus, then multple MAPCodecs could share the storage and the
problem would be solved for this usecase, right?
Right
2) Scenario two is a single JVM/classlaoder with multiple bus's. This is
similar to (1), but the storage could be pre-configured and shareable.
Yes. Btw this is more or less the scenario we're on right now, as we
could have this storage as a shared facility provided by CXF libraries
which can be seen by all apps using them.
3) Scenario three would be multiple apps/jvms/classloader. This is
trickier. One solution would be to allow configuring in a distrubted map
implementation for the storage.
Yes, this is indeed trickier... and would deal with client and final
response endpoint running on different jvm/classloader.
IOW what you're suggesting here is that this might basically be a matter
of having the user configure the storage with the scope/visibility he
needs, right?
Yea. That's kind of what I was thinking. This MAY be combinable with your
disabling of the correlation check so if the message cannot be correlated in
the current storage, just let it through like you originally tried. To avoid
the memory leak, we could timestamp the outgoing exchange and periodically
purge the exchanges based on some sort of configurable timeout. That would
at least cover MOST of the issues.
