[jira] Created: (SLING-1426) Spurious wakeups are not handled correctly

Spurious wakeups are not handled correctly
------------------------------------------

                 Key: SLING-1426
                 URL: https://issues.apache.org/jira/browse/SLING-1426
             Project: Sling
          Issue Type: Bug
          Components: Extensions
    Affects Versions: Extensions Event 2.3.0
            Reporter: Carsten Ziegeler
            Assignee: Carsten Ziegeler
             Fix For: Extensions Event 2.3.2


According to the javadocs, a object.wait() should always be done in a loop in order to catch spurious wakeups.
The JobEventHandler implementation does not wait in a loop which might result in dead locks.

Now waiting in a loop until condition holds true.
