我尝试在执行 Java-EE 批处理执行时获取正在运行的执行。通过 BatchRuntime.getJobOperator().start(JOBNAME,parameters) 首次执行时，一切正常：
BatchRuntime.getJobOperator().getRunningExecutions(JOBNAME)提供正确的执行并
BatchRuntime.getJobOperator().getJobInstanceCount(JOBNAME)导致“1”。
批处理执行完成（使用 BatchStatus.COMPLETED.toString()）。在所有连续运行期间，会发生以下情况：
BatchRuntime.getJobOperator().getJobInstanceCount(JOBNAME)-result 增加，所以它变成 2, 3, ....
BatchRuntime.getJobOperator().getRunningExecutions(JOBNAME)抛出：
javax.batch.operations.NoSuchJobException: Job Name TestBatchProcessing not found

以下是 getRunningExecutions 应该找到的正在运行的 Jobexecution 的属性值（但没有）：
jobProperties: {createTime=2016-08-18 12:45:05.559}
batchStatus: STARTED
exitStatus: null
jobName: TestBatchProcessing
instanceId: 1
executionId: 1
有谁知道这个例外的原因？是否有必要清理作业实例？如果需要，我可以附加具体的代码片段。
预先感谢您的回答。
编辑：getJobInstanceCount 不会一直为 2。每次新作业开始时它都会增加一。
