    java.sql.SQLException: The statement is closed when running jBPM6.2.0.Final

    Steven Hu Newbie

      Recently I am updating from 6.2.0.CR2 to 6.2.0.Final. Everything is ok except the kie-wb always complains the exception when I enable the debug mode: java.sql.SQLException: The statement is closed. I dig out and find the exception will be raised once the database fires any insert or update action. But the process instance and task works well. Please note that my application runs well on WebSphere8.5.5 + jBPM6.2.0.CR2 + Oracle 12c; after I migrate it to jBPM6.2.0.Final + WebSphere 8.5.5 + Oracle 12c, it works well except this exception.

       

      I also test Jiri's rewards-basic project on jBoss EAP6.4 + jBPM6.2.0.Final + H2(jbpm-6-examples/rewards-basic at master · jsvitak/jbpm-6-examples · GitHub), once I enable the debug mode, I still see the same error plus another jdbc exception, but the sample runs well, I can finish all process's task, from creating to completing. So can anyone kindly tell me how to suppress the exception? is it hibernate related issue or jbpm issue?

       

      This is the error from WebSphere:
