decision element in job XML:
<decision id="decide" ref="myDecider"> <next on="goto-step0" to="step0"/> <next on="*" to="step2"/> </decision>
Decider implementation:
public class MyDecider implements Decider { @Override public String decide(StepExecution[] executions) throws Exception { System.out.println("MyDecider#decide(): returning null"); return null; } }
Exception:

I'm not sure how a Decider returns null should be treated by the JBatch runtime (may should fall back to the original exit status?), but I think NPE is not good anyway.
