Some classes return clones of their Properties fields instead of direct references (e.g. connectionProperties on OracleXADataSource). Modify PropertyUtils to handle such cases, and test the ResourceLoader's behaviour.
Add generic type parameters to XAStatefulHolder, XAResourceHolder, XAResourceProducer, XAPool and StateChangeListener interfaces. Add correct concrete classes for JDBC and JMS implementations of these interfaces.
Improve generic interfaces StateChangeListener, XAResourceHolder, XAResourceProducer and XAStatefulHolder. They are now more consistent.
Strengthen definition of XAResourceHolder generic parameter even further.
Add generic parameter to LruEvictionListener.

Jdk6 sql unsupported feature.  Let's try it and well find out how many misbehaving drivers there are.
Merge pull request #32 from rankinc/jdk6-generics

Add generic type parameters.  Reviewed.
Merge pull request #19 from rankinc/cloned-properties

Reviewed.  The defensive coding here is reasonable and can avoid a connection leak.
