Remove GroupValidationResult
Removed GroupValidationResult, replacing it with BeanValidationResult. Modified the ParameterGroup subclasses to use BeanValidator, adding annotations where needed to trigger the validations that had been automatically performed by GroupValidationResult. Added Size annotation, used to verify minimum lengths of maps and collections. Added ClassName annotation, used to verify that a property contains the name of a class that is actually in the classpath. Added another addResult() method to make it easier when replacing calls to GroupValidationResult setResult() method with BeanValidationResult. Issue-ID: POLICY-2059 Change-Id: Id4da24886908723006624c5d53edeb034102299d Signed-off-by: Jim Hahn <jrh3@att.com>
