I get NullPointerException when using ManagedScheduledExecutorService.scheduleAtFixedRate ----------------------------------------------------------------------------------------- Key: WFLY-3570 URL: https://issues.jboss.org/browse/WFLY-3570 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: EE Reporter: Pavel Abizyaev Assignee: Eduardo Martins When I try to run a task with a small period (1 second or less) using ManagedScheduledExecutorService.scheduleAtFixedRate sometimes I get NullPointerException at http://grepcode.com/file/repo1.maven.org/maven2/org.wildfly/wildfly-ee/8.... line 167 (resetHandles is null). I think it occurs when a next task has run before a previous finishes. On 8.1.0 I have the same problem.
