Julius Stroffek commented on DERBY-2420:
----------------------------------------
There are two possible ways how the close method might behave when it should
not be called:
1.) throw an exception and leave the connection in the unchaged state.
2.) close the connection, do cleanup and throw the exception.
For now, embedded driver (EmbeddedConnection) throws the exception does not
perform all the cleanup and leaves the connection in unusable state. The chain
of function calls from EmbedPooledConnection.close -> EmbedConnection.close.
People usually do not care much about the exceptions thrown by close method and
expecting that there is not much they can do if it is not possible to close the
connection. Therefore I think option 2 is a better choice. The exception about
inproper usage would be thrown and even after that it would not be possible to
use that connection anymore.
> XAConnection close method should throw an exception if it is called when the
> global transaction is associated with the connection.

> Project: Derby
> Issue Type: Bug
> Components: Network Client
> Reporter: Julius Stroffek
> Assignee: Julius Stroffek
> Priority: Minor
> Fix For: 10.3.0.0
>
>
> As comments show in DERBY-2220 The Distributed Transaction Processing: The XA
> Specification forbids for a transaction manager or an application to call
> XAConnection.close method when there is a global transaction associated with
> the XA connection.
> Currently,
> Embedded driver throws the exception but the connection is left in a state
> when it cannot be used anymore and the locks held by the transaction can not
> be released later.
> Network driver allows the call of the method and closes the connection.
