Description

I ran into a situation where a MutableBoolean implementation was actually useful and wondered if
Commons Lang might consider adding the implementation. My example:

final MutableBoolean success = new MutableBoolean(false);
doSomething(new MyCallbackInterface() {
public void callback()

{ // do something... success.setValue(true); }

);

Basically the ability to change the boolean's state within an inner class, where the declared object must
be 'final'. Pretty obscure I realize, but this turned out to be quite useful in the application I was working
on.
