      Description

        Finalisation for FileInputStream/FileOutputStream/RandomAccessFile streams that share the same native FileDescritor needs improvement. Currently a counter is used to keep track of streams which reference the same native FD. A close() on one of the streams means other streams are not properly notified of the event.

        Best approach is to modify fileDescriptor so that FileInputStream/FileOutputStream/RandomAccessFile classes can register with them and ensure streams are correctly closed out at close() time or when finalizer gets to run.
