      Description

      When executing a job B in a currently running job A and calling B.join() in A, the following exception is thrown :

       

      Exception in thread "pool-2-thread-2" java.lang.NullPointerException
        at org.xwiki.job.AbstractJob.jobFinished(AbstractJob.java:262)
        at org.xwiki.job.AbstractJob.runInContext(AbstractJob.java:211)
        at org.xwiki.job.AbstractJob.run(AbstractJob.java:189)
        at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149)
        at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)
        at java.lang.Thread.run(Thread.java:748)

      After that, B.join() never returns, therefore not allowing the job A to end properly.
