5.0 b26Fixed
The documentation of the class javax.sound.midi.MidiDevice contains at least one obsolete and confusing comment. This should be remove. Other issues should be explained more detailled.

- (class description:) "To this end, it
 * typically also implements the <code>{@link Transmitter}</code> or
 * <code>{@link Receiver}</code> interface (or both), or has access to objects that do."
MidiDevices do not implement the interfaces Transmitter and Receiver. The wording should be changed to something like this: "A <code>MidiDevice</code>
 * can be a transmitter or a receiver of MIDI events, or both. Therefore, it
 * can provide <code>{@link Transmitter}</code> or
 * <code>{@link Receiver}</code> instances (or both). Typically, MIDI IN ports provide Transmitters, MIDI OUT ports and Synthesizers provide Receivers. Sequencers typically provide Transmitters for playback and Receivers for recording."

- for newcomers, it is not obvious how to detect if a MidiDevice represents a hardware MIDI port. The usual code snippet used for this (below) should be included in the documentation.
MidiDevice device = ...;
if ( ! (device instanceof Sequencer) && ! (device instanceof Synthesizer)) {
    // we're now sure that device represents a MIDI port
    // ...

- obsolete and commented out code (ThruTransmitter) should be removed.
