Error Messages:
Exception in thread "Thread-7" java.lang.AssertionError: Could not find

> When user needs to refresh existing or add a new jar to HS2, it needs to 
> restart it. As HS2 is service exposed to clients, this requires scheduling 
> maintenance window for every jar change. It would be great if we could avoid 
> that.
