[infinispan-issues] [JBoss JIRA] (ISPN-8853) Registering interposed synchronization fails in async operation with implicit transaction

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 Assignee: Radim Vansa Fix For: 9.2.1.Final {{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.
