Does osworkflow-2.5.0.jar use ThreadLocal?

[Samer Kanjo-2]

Hi,
I am using [b]osworkflow-2.5.0.jar[/b] in an application deployed in Websphere 6.1.0.13.

1. Does this jar file use [b]ThreadLocal[/b] variables?
2. If yes, then does it 'clean' up the ThreadLocal variable before returning the thread to the threadpool?

Please post your replies/views soon.

An interesting question. I had a look at the source and found that the use of ThreadLocal was not added until version 2.8.0.

In version 2.8.0 it is used in to store a cache of actions. The actions are stored to the cache on calls to AbstractWorkflow.isActionAvailable. When the workflow is transitioned using AbstractWorkflow.transitionWorkflow the cache is cleared.

There is no specific code to clean up the cache.
