----------------------------------------

Using this component dont throw the other exception but log this on the console:

[Token] lock owner 'Job(17)' tries to unlock token '182' which is not locked
execute the node 1 time, log the above line, execute again the node and throw a NullPointerException:

In this line (I add some logs for see whats happen) the null is job variale i think.
if (job.execute(jbpmContext)) {

>          Issue Type: Feature Request
>          Components: BPM
>    Affects Versions: 2.0.3.CR1
>         Environment: Seam 2.0.3, JBPM 3.2.2

> JBPM Job Execution using JobExecutorServlet doesn't work in Seam. Attached are modified sources to turn JobExecutorServlet into a Seam component and to have it use Seam's contexts and transactions.
> This is probably not the best way to do it but it works for me where I'm using it. There is a proper solution in the making - see related issues.
