      A DESCRIPTION OF THE REQUEST :
      The current JRE release does not support releasing of a java.nio.MappedByteBuffer.

      Documentation says: "A mapped byte buffer and the file mapping that it represents remain valid until the buffer itself is garbage-collected."

      Therefore it is not possible to delete the underlying file on Windows, if has been mmap'd before (and the MappedByteBuffer has not been GC'd).


      JUSTIFICATION :
      Let java.nio.MappedByteBuffer implement the interface java.io.Closeable

      or

      add a method release().

      Either way should immediatly release all system resources referenced by the mapped byte buffer.
