Well, reflection is a bad idea too :-) A better solution is to use a 
wrapper like jdkCompat ( i.e. a base class with the 1.3 implementation,
extended with a 1.4 impl ). This class could include other 1.4 methods
and their 1.3 equivalent, if any.

This would allow implementing the correct stuff, instead of failing.
