BrokerImpl using thread class loader?

[Dain Sundstrom]

The BrokerImpl class initializes the _loader to Thread.currentThread 
().getContextClassLoader() when constructed (when an EM is  
constructed).  This cl is used while loading the mappings file.  This  
causes the entity classes to be loaded from the thread context class  
loader instead of the class loader specified in the PersistenceUnit.   
Is this expected behavior?

In the mean time, I'll code around it.
