Inside your C++ method you must destroy objects you create, or you
must later do a Java call to some C++ code that kills them. You can
use addShutDownHook in Java to arrange for code to run at shutdown.

It should not be considered an error when the user starts something
already started or stops something already stopped. This applies
to browsers, services, editors... It is inexcusable to 
punish the user by requiring some elaborate sequence to atone,
e.g. open the task editor, find and kill some processes.
