Summary: Trans-Attrib 'Supports' Fails in Entity

Initial Comment:
I have an entity bean that I labeled with:

<trans-attribute>Supports</trans-attribute>

When I access the bean from a test case (and thus 
there is no transaction), I get a NullPointerException 
in JDBCStoreManager.getApplicationTxDataMap(). 

This is happening because the first thing that happens 
in this function is this call:

Transaction tx = tm.getTransaction() 

which returns null. A moment later, because there is 
no existing map, this line is executed:

tx.registerSynchronization(synch);

and that's all she wrote. I'd submit a patch, but I 
don't have any clue how anything outside this method 
works! :)

Changing the trans-attribute to Requires is a work 
around.

Point taken, I did actually come across this information in 
searching for a resolution. My comment about setting it to 
Requires being a "workaround" was forgetful on my part.

But, a NullPointerException is still being thrown. Perhaps 
the EJB verifier should catch this and not allow the bean 
to deploy, but trapping this error would certainly be an 
improvement.

Please read the EJB-2.0 spec. on chapter 17.4.1 stating 
that a Entity Bean using EJB 2.0 Container-Managed 
Peristance that "Supports", "NotSupported" and "Never" is 
not allowed !
