Error description
When using the batch features, after making a change to the server configuration causing a restart of one or more components of the batch feature, a NullPointerException in the com.ibm.jbatch.container.api.impl.JobOperatorImpl class may be seen. This might be seen, for example, when using the javax.batch.operations.JobOperator API provided by the "batch-1.0" feature. For example, here is an exception stack trace when the "start" method of JobOperator is invoked. ERROR: java.lang.NullPointerException javax.batch.operations.JobStartException: java.lang.NullPointerException at com.ibm.jbatch.container.api.impl.JobOperatorImpl.start(JobO peratorImpl.java:178) at com.ibm.jbatch.container.api.impl.JobOperatorImplSuspendTran .start(JobOperatorImplSuspendTran.java:156) at Typically this would be occur after a (subsequent) CWWKY0008I message appears in messages.log, after the configuration change. This message appearing a second time in messages.log (the first time corresponding to the initial activation of the feature), would indicate that the batch kernel component had reinitialized (after a configuration change involving the batch components themselves or components which are part of the batch dependency tree).

Problem conclusion
The dependency on the BatchSecurityHelper was changed from OPTIONAL to MANDATORY. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.7. Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
Temporary fix
Recycling the server after such a server configuration change should bypass this problem.
