[JSR308] Note about asDefined method

[Mahmood Ali]

Hi Artemus,

The method sounds good for your purposes.

However, it would fail for cases where type variables extend each
other, like in:

    class MyClass<E, V extends E> { V field; }

You can use a while-loop instead of the first 'if' or call the method
recursively.

Regards,
Mahmood
