I’d love to see this work proceed for Infinispan, since we want to do the same thing for
ModeShape, which uses (but does not hide or encapsulate) Infinispan.

Randall, that is *definitely* the case and is certainly true for Hibernate. The work
involved:
* correctly resolving ClassLoaders based on the activated bundles
* supporting multiple containers and contexts (container-managed JPA, un-managed
JPA/native, etc.)
* fully supporting OSGi/Blueprint services (both for internal services as well as
externally-registered)
* bundle scanning
* generally working towards supporting the dynamic nature
* full unit-tests with Arquillian and an OSGi container
It's a matter of holistically supporting the "OSGi way" (for better or
worse), as opposed to simply ensuring the library's manifest is correct.
There were a bloody ton of gotchas and caveats I hit along the way. That's more
along the lines of where I might be able to help.
I'm even more interested in this effort so that we can support hibernate-infinispan
2nd level caching within ORM. On the first attempt, I hit ClassLoader issues [1]. Some
of that may already be resolved.
The next step may simply be giving hibernate-infinispan another shot and correcting
things as I find them. In parallel, feel free to let me know if there's anything
else! ORM supports lots of OSGi-enabled extension points, etc. that are powerful for
users, but obviously I don't have the Infinispan knowledge to know what would be
necessary.
Thanks!

Brett, correct me if I’m wrong, but isn’t there a difference in making some library
*work* in an OSGi environment and making that library *naturally fit well* in an
OSGi-enabled application? For example, making the JAR’s be OSGi bundles is easy and
technically makes it possible to deploy a JAR into an OSGi env, but that’s not where the
payoff is. IIUC what you really want is a BundleActivator or Declarative Services [1] so
that the library’s components are readily available in a naturally-OSGi way.

for hibernate-infinispan to work in OSGi.
