[<joh...@co...>]

Update of /cvsroot/commonjava/commonjava-projects/commonjava-reflection/src/java/org/commonjava/reflection
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv10722/src/java/org/commonjava/reflection

Modified Files:
	Reflector.java 
Log Message:
added null check/exception throw to getMethod() and getConstructor() in Reflector, to make it easier to debug actual problems. Was throwing NPE from higher-level of call stack, which meant nothing to outside observer.
