Summary: ServletRequestCleanupService throws RuntimeException when a portlet is rendered asynchronously in parallel mode
Key: JS2-1283
URL: https://issues.apache.org/jira/browse/JS2-1283
Project: Jetspeed 2
Issue Type: Bug
Reporter: Woonsan Ko
Assignee: Woonsan Ko
Fix For: 2.2.3
In a load testing, I found the following error logs in jetspeed.log:
--------------------------------------------------------------------------------------------

--------------------------------------------------------------------------------------------
Apparently the async worker thread is not provided with the callbacks thread local list by the filter (ServletRequestCleanupFilter).
So, to avoid the error, each job execution should be able to initialize and clear every time somehow.
Also, JSSubject.doAsPrivileged(...) call is made in WorkerImpl currently. The problem is this can call ServletRequestCleanupService.addCleanupCallback() in its #setSubject(..) method. However, it is not recommendable to improve the WorkerImpl to initialize/clean up using ServletRequestCleanupService because a worker class might be provided by the container (e.g, commonj worker monitor) and WorkerImpl is just a default worker thread implementation.
Therefore, the JSSubject.doAsProviledged(...) call should be moved to the job implementation class as well.
