Added: src/main/org/jboss/ejb/plugins
EntityCreationInterceptor.java
Log:
Breaks entity create methods into a call down the invokeHome chain to
invoke ejbCreate and one down the invoke chain to invoke ejbPostCreate.
This makes ejbPostCreate look like a standard business method invocation.
This should eliminate the "INSERTING AN ALREADY EXISTING BEAN" bugs.
