-------------------------------------
Summary: NPE in FalconWorkflowEngine::isActive() method when
FalconJPAService is not used
Key: FALCON-2107
URL: https://issues.apache.org/jira/browse/FALCON-2107
Project: Falcon
Issue Type: Bug
Affects Versions: 0.10
Reporter: Balu Vellanki
Assignee: Balu Vellanki
Priority: Blocker
Fix For: 0.10
When attempting any schedulable entity actions, Falcon is attempting to do
getNativeWorkflowEngine().isActive(entity) -- which throws an NPE when
FalconJPAService is not enabled in startup.properties.

Confirmed with [~pallavi.rao] that the optimal solution is to catch NPE and
return false in the isActive(...) method.
