> A Java-level deadlock was encountered while running {{org.jboss.as.test.integration.jca.workmanager.LongRunningThreadsCheckTestCase}}. The thread dump is attached.
> This occurred during testing of the new thread pool (WFLY-5332 and related), but it seems unlikely to be caused by this change, unless the new pool's scheduling behavior differed enough from the default that it exposed an already-existing race condition. The deadlock was hit just once in more than 10 runs.
> This is the deadlock:
> {noformat}
> Found one Java-level deadlock:

> "DeploymentScanner-threads - 2":
> waiting for ownable synchronizer 0x000000075357cef0, (a java.util.concurrent.locks.ReentrantLock$NonfairSync),
