I think that is a valid assumption. According to the code for ApplicationHandle it will always return the application instance id even after the application has ended. This is also true for the method getApplicationDescriptor. I think the javadoc should be improved to make this clear. I'm not sure about the abstract method ApplicationHandle.getState. I also find it strange that there is no defined state for STOPPED. What do you expect to be returned from ApplicationHandle.getState after the application has ended? Returning STOPPING seems strange.
