---------------------------------

             Summary: Registering interposed synchronization fails in async operation with implicit transaction
                 Key: ISPN-8853
                 URL: https://issues.jboss.org/browse/ISPN-8853
             Project: Infinispan
          Issue Type: Bug
          Components: Core, Transactions
    Affects Versions: 9.2.0.CR2
            Reporter: Radim Vansa


{{TransactionTable.enlist}} calls {{transactionSynchronizationRegistry.registerInterposedSynchronization(sync);}} but when an async operation is invoked with implicit transaction, the thread-local transaction is suspended. That can result in 
{code}
java.lang.NullPointerException
	at java.util.concurrent.ConcurrentHashMap.get(ConcurrentHashMap.java:936)
	at org.jboss.as.txn.service.internal.tsr.TransactionSynchronizationRegistryWrapper.registerInterposedSynchronization(TransactionSynchronizationRegistryWrapper.java:69)
{code}

I guess that since {{TransactionSynchronizationRegistry}} does not offer a variant that would accept the transaction as parameter we need to wrap the call with resume & suspend.
