Fixes to allow to use jikes to compile and produce less warnings:

1. Replace catch(Exception) by catch(RuntimeException) when only RuntimeException can be throws

2. Make sure that inner classes does not use the same name for parameters as parent scope, see  http://domino.watson.ibm.com/syssftpr/JavaTech/Jikes.nsf/Named/SunQuery8
