Julius Stroffek commented on DERBY-2421:
----------------------------------------

If the XAConnection object is going to be garbage collected, I think It is 
quite safe to rollback the global transaction associated with the connection. 
Otherwise, the locks held by the transaction will not be released later. I 
think, this is not covered by the JTA spec and also not by "Distribute 
Transaction Processing: XA Specification". I also can not see a much sense in 
making a difference in behavior between embedded and network driver - so I 
would do the same for both.

Please correct me if I am wrong. Any other opinions?

> implement the finalize method separately (currently, the close method is 
> called) for both client and network drivers.

> If the garbage collection will be performed on XAConnection objects the 
> correct cleanup have to be performed and also the roll-back of the whole 
> global transaction should be considered and discussed here.
