Any way to further optimize Java reflective method invocation?

Question

I am wondering if there are any additional optimizations I can implement to improve the speed of reflective invocations in Java. Not that the performance is prohibitive, but

Answer 1

If the cost of invocation is less than 10% of the cost of what goes on in the method, it's hardly worth worrying about.

You can determine that by running it 10^6 times in a loop, with and without the guts of the routine. Time it with a stopwatch, so seconds translate to microseconds.
