When trying to retrieve the running executions of a job but I got a NPE:
Caused by: java.lang.NullPointerException at org.jberet.runtime.JobExecutionImpl.getJobName(JobExecutionImpl.java:141) at org.jberet.operations.JobOperatorImpl.getRunningExecutions(JobOperatorImpl.java:157) at ch.adnovum.monexio.server.batch.rs.BatchOperatorServiceBean.getRunningJobIds(BatchOperatorServiceBean.java:143) at ch.adnovum.monexio.server.batch.rs.BatchOperatorServiceBean.assertAtomicJob(BatchOperatorServiceBean.java:94) at ch.adnovum.monexio.server.batch.rs.BatchOperatorServiceBean.start(BatchOperatorServiceBean.java:54)

looking at the code, i could not tell what the problem was, could some body give me some hints?
(I possted a question http://stackoverflow.com/questions/39074855/jberet-npe-for-jobexecutiongetjobname as well).

thanks in advance.
