[jira] [Created] (APEXCORE-617) InputNodeTest intermittently fails with ConcurrentModificationException

Vlad Rozov created APEXCORE-617:
-----------------------------------

             Summary: InputNodeTest intermittently fails with ConcurrentModificationException
                 Key: APEXCORE-617
                 URL: https://issues.apache.org/jira/browse/APEXCORE-617
             Project: Apache Apex Core
          Issue Type: Bug
            Reporter: Vlad Rozov
            Assignee: Vlad Rozov
            Priority: Minor


InputNodeTest.emitTestHelper uses deprecated inherently unsafe Thread.stop(). Thread.stop() does not immediately stops the thread, the JVM waits for a safepoint to raise ThreadDeath exception on the target thread. This leads to a race condition and possible ConcurrentModificationException.
