The use case is incomplete. It does not cover libraries. Just ask the OpenJDK guys about libraries like Ncurses and OpenSSL. They were discussing library problems on the OpenSSL mailing list in the past. You see, the application will remain loaded, but Java (and other languages like .Net) will load the shared objects multiple times as functions are needed (and then unload the shared object when the call is done). The subsequent accumulated memory leak eventually crashes the app or device. Jeff
