org.springframework.batch.core.step.AbstractStep execute Encountered an error executing the step java.lang.StackOverflowError at java.util.HashMap.getEntry(Unknown Source) at java.util.HashMap.get(Unknown Source) at com.ibm.websphere.rsadapter.DB2DataStoreHelper.findMappingClass(DB2DataStoreHelper.java:529) at com.ibm.websphere.rsadapter.DB2DataStoreHelper.findMappingClass(DB2DataStoreHelper.java:545) at com.ibm.websphere.rsadapter.DB2DataStoreHelper.findMappingClass(DB2DataStoreHelper.java:545)

to solve i just rerun the process and everything goes fine, but the infinite loop is wierd. What can i do to avoid it?
