title: Spring Batch multiple jobs at once started?
body: <p>In my spring batch i see following logs.</p>
  
  <pre><code>INFO 5572 --- [   scheduling-1] o.s.b.c.l.support.SimpleJobLauncher      : Job: [FlowJob: [name=sample]] launched with the following parameters: [{JobID=x}]
  INFO 5572 --- [           main] o.s.b.c.l.support.SimpleJobLauncher      : Job: [FlowJob: [name=sample]] launched with the following parameters: [{run.id=1, JobID=y}]
  INFO 5572 --- [   scheduling-1] o.s.batch.core.job.SimpleStepHandler     : Executing step: [step1]
  INFO 5572 --- [           main] o.s.batch.core.job.SimpleStepHandler     : Executing step: [step1]
  </code></pre>
  
  <p>Is this same log lines repeated by two threads or two jobs started at once ?</p>
