/** All callback definitions must derive from this interface. Any
* derived interfaces must define a single public method named "callback".
* You are responsible for deregistering your callback (if necessary)
* in its {@link Object#finalize} method. If native code attempts to call
* a callback which has been GC'd, you will likely crash the VM. If
* there is no method to deregister the callback (e.g. atexit
* in the C library), you must ensure that you always keep a live reference
* to the callback object.
* A callback should generally never throw an exception, since it doesn't
* necessarily have an encompassing Java environment to catch it. Any
* exceptions thrown will be passed to the default callback exception
* handler.
