Rupert Westenthaler created STANBOL-651:
-------------------------------------------
Summary: EventJobManager does not finish if an Engine fails that
is not the last Engine in the EnhancementChain
Key: STANBOL-651
URL: https://issues.apache.org/jira/browse/STANBOL-651
Project: Stanbol
Issue Type: Bug
Components: Enhancer
Affects Versions: 0.9.0-incubating
Reporter: Rupert Westenthaler
Assignee: Rupert Westenthaler
Fix For: enhancer-0.10.0-incubating
The EventJobManager does not complete an EnhancementJob if the following
Situation occurs
* An EnhancementEngine fails
* The failed engine is not the last on in the EnhancementChain
* No other engines are executed in parallel
The reason for that is the the EnhancementJobHander (asyc execution using
osgi.service.event framework) needs to notify the EventJobManagerImpl if an
EnhancementJob completes. However in the above situation this does not occur
and because of the the EventJobManagerImpl waits "forever" for the completion
of the job - similar to a deadlock.
To solve this the EnhancementJob#isFinished() needs to be adopted to correctly
report an Job as "finished" if EnhancementJob#isFailed() == true and not other
engines are executed in parallel.
