    Description

      We observed some problems with the scheduler component. One issue is, that the kaha db files from the scheduler won't be removed. On further investigation I found a potential cause which could be exposed by a test. When messages are send concurrently delayed by the scheduler, messages will be lost. It seems that the schedule method on JobSchedulerImpl should be synchronized.
