David Jencks commented on GERONIMO-4448:
----------------------------------------
I'm not sure exactly what you see as the problem here.... IMO the behavior
when "resuming" a non-suspended transaction is not specified so we don't need
to check that the argument to resume is in fact suspended.
However..., what is a valid transaction? Does the jta spec define this
anywhere?
For instance.... can you suspend a transaction that is prepared but not
committed? How about if you've called setRollbackOnly() on it?
IIRC (from many years ago) the jta spec tends to not specify a lot of this
behavior.

> Project: Geronimo
> Issue Type: Bug
> Security Level: public(Regular issues)
> Components: transaction manager
> Affects Versions: 2.2
> Reporter: Lin Sun
> Assignee: Lin Sun
> Fix For: 2.2

> Currently, the resume manager resumes pretty much any transaction as long as
> the transaction is not null and is an instance of TransactionImpl.
> I think this is incorrect. Per the jTA 1.1 spec, page 13:
> Suspending and Resuming a Transaction
> A call to theTransactionManager.suspend method temporarily suspends the
> transaction that is currently associated with the calling thread. If the
> thread is not
> associated with any transaction, anull object reference is returned;
> otherwise, a valid
> Transaction object is returned. TheTransactionobject can later be passed to
> the
> resume method to reinstate the transaction context association with the
> calling thread.
> TheTransactionManager.resumemethod re-associates the specified transaction
> context with the calling thread. If the transaction specified is a valid
> transaction, the
> transaction context is associated with the calling thread; otherwise, the
> thread is
> associated with no transaction.
> Transaction tobj = TransactionManager.suspend();
> ..
> TransactionManager.resume(tobj);
> A simple test below would reveal the prob:
> {code}
> public void testResume1() throws Exception {
> Transaction tx;
> assertEquals(Status.STATUS_NO_TRANSACTION, tm.getStatus());
> tm.begin();
> assertEquals(Status.STATUS_ACTIVE, tm.getStatus());
> tx = tm.getTransaction();
> assertNotNull(tx);
> assertEquals(Status.STATUS_ACTIVE, tx.getStatus());
>
> tm.commit();
> assertEquals(Status.STATUS_NO_TRANSACTION, tm.getStatus());
> assertNull(tm.getTransaction());
>
> try {
> tm.resume(tx);
> fail();
> } catch (InvalidTransactionException e) {
> // expected
> }
> }
> {code}
