------------------------------
Please also add that this affects jbpm 4.3.
Also, I am seeing this error when a process is ended by a "end" activity:
java.lang.NullPointerException

However, I do not understand why this doesn't just happen all of the time, because:
org.jbpm.pvm.internal.wire.usercode.UserCodeReference.getObject(UserCodeReference.java:47)
is
public Object getObject(Execution execution) {
return getObject(null, execution);
}
So null is always passed in as the value for the processDefinition variable, which is what
causes the NPE in the first place.
NullPointerException is thrown when forcing a process to end having
attached end event listener
