The specification for javax.sound.midi.Sequencer.SyncMode.equals says:
--
public final boolean equals(Object obj)
    Determines whether two objects are equal. Returns true if the objects are identical
    Overrides:
        equals in class Object
    Parameters:
        obj - the reference object with which to compare
    Returns:
        true if this object is the same as the obj argument, false otherwise
    See Also:
        Object.hashCode(), Hashtable
--

  The description of the method does not give a univocal presentation about what objects are supposed to be equal. Let's consider the following pair of objects:

Sequencer.SyncMode sMode1 = new MySyncMode("one");
Sequencer.SyncMode sMode2 = new MySyncMode("one");

  The present spec can not say definitely whether these 2 objects are equal. One can argue that the following statement answers the question:
--
Returns:
    true if this object is the same as the obj argument, false otherwise
--

  However "the same" can be treated in different ways. For example, see the "return" section for java.lang.Long:
--
Returns:
    true if the objects are the same; false otherwise.
