> URL: https://issues.apache.org/jira/browse/APEXMALHAR-2508
> Project: Apache Apex Malhar
> Issue Type: Bug
> Reporter: Ajay Gupta
> Assignee: Ajay Gupta
> Priority: Minor
>
> CacheManager initializes the Timer (refresher) only if refreshTime is not
> null. However, in deactivate, before cancelling the timer, there is no null
> check leading to NullPointerException.
> Solution : Add a null check before cancelling the timer.
