(bf) MappedByteBuffer.release()/close() to release system resources

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.
