The m_activityObject and m_serviceObjects are no longer plain jobjects. Instead they are constructed with a jobject. The constructor makes it a global ref, which the destructor then frees. The destruction happens when the stdlib exit() is called. However, since the terminateQt() function already had released the global ref, the destruction of the objects crashes the application with a JNI APPLICATION ERROR in Android logs. In addition since the the code only ever freed the reference to a reference, the actual reference was leaked.
