I already started https://github.com/ops4j/org.ops4j.pax.jms for JMS a
while ago so you are maybe interested in adding the pooling-feature
there also?
In fact pooling and recovery can be nicly integrated into OSGi using the
service factory, so a switch over would be simply register/unregister a
service with a new underlying connection, pooling can be done with
ServiceFactorys that share a fixed set of connections. Just don't know
if this works well with XA

I began to work on a small project which aims at providing support for
pooled XA-enabled connections for JDBC and JMS.
For JDBC, the problem was already solved in pax-jdbc by using either
pax-jdbc-pool-aries when deploying the Aries/Geronimo transaction
manager, and by using pax-jdbc-pool-narayana when using the Narayana
transaction manager.
However, there's absolutely no support for JMS.
So what I've been doing is to reuse the geronimo JCA connector, make
it independent on Geronimo TM and add support for Narayana, use a
clone of the old tranql adapter for JDBC and rewrite a new JMS 2.0
compatible adapter for JMS.
It's not in a usable state yet, but I wanted to give an heads-up.
My plan is to make the pooling almost transparent in OSGi, and reuse
it instead of the connection pooling I added to Karaf a few weeks ago
which does not support XA or recovery:
https://github.com/apache/karaf/tree/master/jms/pool
and maybe to plug it into pax-jdbc to replace pax-jdbc-pool-aries and
pax-jdbc-pool-narayana.
The source code is currently available at:
https://github.com/gnodet/org.ops4j.pax.transx
Cheers,
