[Digester] Performance Improvements

["Gregory M. Messner" <gm...@titan.com>]

First off, I think the digester package is great, however it is a bit 
slow, poking around I noticed that each time a method was invoked by 
CallMethodRule, SetNextRule, SetRootRule, and  SetTopRule the 
java.lang.reflect.Method was looked up each time. I made a small change 
in each of these classes that uses MethodUtils.getAccessibleMethod() or 
MethodUtils.getMatchingAccessibleMethod() (depending on the 
useExactMatch flag) to get the java.lang.reflect.Method instance, saves 
it and then directly calls invoke() on the Method instance.  On a 
SunBlade 100 this small change resulted in a 10X speed improvement.

I have created patch files for the changes but wasn't sure how to 
deliver them, should they all be put in the body of a single email, each 
one sent in its own email, or should they be attached to an email?  As 
soon as someone lets me know the correct way to submit the patches I'll 
send them in.

Greg
