IIOPTimeoutTestCase sometimes fails ----------------------------------- Key: WFLY-12860 URL: https://issues.redhat.com/browse/WFLY-12860 Project: WildFly Issue Type: Quality Risk Components: IIOP, Test Suite, Transactions Affects Versions: 18.0.1.Final Reporter: Michael Musgrove Assignee: Tomasz Adamski Priority: Major Fix For: No Release The test has been seen to fail twice in the last few months (see [link title|https://github.com/wildfly/wildfly/pull/12833] ,for example) and it would be useful to isolate why it fails. The stack trace also shows an unexpected NPE coming from the transaction subsystem which on code inspection should never happen: {code} &amp#27;[0m&amp#27;[31m06:26:32,517 ERROR [stderr] (p: default-threadpool; w: Idle) java.lang.NullPointerException &amp#27;[0m&amp#27;[31m06:26:32,517 ERROR [stderr] (p: default-threadpool; w: Idle) at java.base/java.util.ArrayDeque.addFirst(ArrayDeque.java:287) &amp#27;[0m&amp#27;[31m06:26:32,518 ERROR [stderr] (p: default-threadpool; w: Idle) at java.base/java.util.ArrayDeque.push(ArrayDeque.java:580) &amp#27;[0m&amp#27;[31m06:26:32,518 ERROR [stderr] (p: default-threadpool; w: Idle) at org.jboss.jts@5.10.1.Final//com.arjuna.ats.internal.arjuna.thread.ThreadActionData.pushAction(ThreadActionData.java:85) {code}
