LocalTransactionContext.getCurrent().findOrImportTransaction(xid, 0).getTransaction()

The Narayana SubordinationManager importTransaction can return transactions that are recovered and so these will have a status of COMMITTING which means they can't have a sync registered.

WFTC registers syncs:
1. getEntryFor:258, JBossLocalTransactionProvider (org.wildfly.transaction.client.provider.jboss)
2. transactionCreated:281, EJBSuspendHandlerService (org.jboss.as.ejb3.suspend)
2. TransactionManagerService lambda

It does this without checking if the TX status is committing.

Ends up with this:

Caused by: java.lang.IllegalStateException: ARJUNA016082: Synchronizations are not allowed! Transaction status isActionStatus.COMMITTING

We can't use our own subordinationmanager as we want to resume the TX and so doing that gets:

Caused by: javax.transaction.InvalidTransactionException: WFTXN0002: Transaction is not a supported instance: TransactionImple < jca-subordinate, BasicAction: 0:ffff0a247413:223d3910:58b06e37:14 status: ActionStatus.RUNNING >
