The compiled jython will pay a performance penalty for being
dynamic. Where Java knows the type of objects, and can deduce the
correct method to call at compile time (well, some of the time,
anyway), the jython code will have to do a method search at run time.
Chance are, if you're supposed to be wwriting in Java, your
application isn't sensitive enough to the performance of the code for
this to matter.
