ValidateMethodInterceptor should not be part of public API so make it package private.
Integrated in Onami-Validation #14 (See https://builds.apache.org/job/Onami-Validation/14/)
ONAMI-80 Make interceptor package private and remove setter because it'll never be used (Revision 1444524)
Result = FAILURE
Fixed in 1444524
Also, setter method setValidatorFactory() is useless because it's not used and is out of reach in case ValidateMethodInterceptor class is not public. So it can be removed too.
