Michael Youngstrom resolved JBSEAM-4552.
----------------------------------------

    Resolution: Done


fixed.

I modified HibernateSessionProxy and EntityManagerProxy and their Hibernate Search counterparts to both use JDK proxy instead.

I converted the existing HibernateSessionProxy and EntityManagerProxy to interfaces and used those interfaces as the proxy interface to help maintain compatibility with any code that may be depending upon Session and EntityManager to be of that type.

All build tests pass
All tests for my local Hibernate 3.5 JPA 2 application pass and allow method calls to JPA 2 methods
Hibernate Booking still works on AS 5.1

> When I attempt to invoke a JPA 2 method on a Seam managed EntityManager I get an AbstractMethodError.  This is because org.jboss.seam.persistence.EntityManagerProxy doesn't implement any of the new JPA 2 methods.
> I believe if we're targeting 2.2.1 as something that will work in AS 6 we should fix this.
> I'll be committing a fix shortly unless someone stops me. :)
