[WFTC-126] suppressed deprecation warning

[istudens]

Issue: https://issues.redhat.com/browse/WFTC-126

[istudens]

@chengfang I thought this would be about code change to a newer class of com.arjuna.ats.jbossatx.jta.TransactionManagerDelegate, but it is used there for instance checking only and so it can't be changed.

[chengfang]

com.arjuna.ats.jbossatx.jta.TransactionManagerDelegate has been deprecated with no replacement. So the related check in the code will not be needed now or in the future. If so, that block can be removed, if it's deemed safe to do so.

I think I would keep the deprecation warning for now, until we know it's safe to remove that check.

When will we know it is safe to remove it. The class has been deprecated, but it is still there. Hence the check might be needed, right?

[chengfang]

@mmusgrov any idea who are likely still using this deprecated class: com.arjuna.ats.jbossatx.jta.TransactionManagerDelegate?

BTW, I cloned this issue to https://issues.redhat.com/browse/JBTM-3808, since this class is still used in narayana itself. So after its use is removed from narayana itself, we'll have better idea its impact in wildfly-transaction-client.
