Hi,
I have found a problem with createObject method of ObjectFactoryImpl class :
| public Object createObject(ObjectInfo objectInfo) {
| clearRegistry();
| return getObject(objectInfo);
| }
|
this code is not thread safe
This can cause errors like
java.lang.RuntimeException: closed JbpmContext more then once... check your
try-finally's around JbpmContexts blocks
at org.jbpm.JbpmContext.popThisContextFromTheStack(JbpmContext.java:493)
at org.jbpm.JbpmContext.close(JbpmContext.java:139)
due to bad context creation when calling JbpmConfiguration.createJbpmContext
from a lot of different threads
It's difficult to produce, so try adding a sleep call after clearRegistry() in
createObject method, and you will see the problem ...
| public Object createObject(ObjectInfo objectInfo) {
| clearRegistry();
| try {
| Thread.sleep(2000);
| } catch (InterruptedException e) {
| // TODO Auto-generated catch block
| e.printStackTrace();
| }
| return getObject(objectInfo);
| }
|
|
I think adding a synchronized will correct the bug.
| public synchronized Object createObject(ObjectInfo objectInfo) {
| clearRegistry();
| return getObject(objectInfo);
| }
|
Regards,
Emmanuel
