Hi.
WIth jbpm 4.3 I modified  SubProcessActivity in order to have the same execution id of principal process in the sub processes. 

Instad of
    ExecutionImpl subProcessInstance = (ExecutionImpl) processDefinition.createProcessInstance(null, execution);
I put
    ExecutionImpl subProcessInstance = (ExecutionImpl) processDefinition.createProcessInstance(execution.getId(), execution);
 
Now I installed jbpm 4.4 and I'm trying to do the same change. I modified SubProcessActivity class and then I overwrote SubProcessActivity.class and SubProcessBindings.class in jbpm.jar. But when I start the main process I get the following error:

It seems to refer to old SubProcessBindings.class but I checked that jbpm.jar in tomcat's lib and in the application lib is the newer version.
What's wrong?
Thanks for your help.
