>                 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.
