The ChainingInterceptor does not properly parse the incoming included or excluded methods.
If passed in values, via <param name="includedMethod">foo,bar</param>, the interceptor ends up with a collection of one string "foo.bar".

For example the ValidationInterceptor, a subclass of MethodFilterInterceptor, uses the TextParseUtil.commaDelimitedStringToXXX to properly parse the param. I believe this is the same behavior ChainingInterceptor should exhibit.
