> MethodValidatorMetaBeanFactory.buildMethodConstraints() fill the ParameterAccess access
with ParameterTypes. I think it must be method.getGenericParameterTypes().
> MethodValidatorMetaBeanFactory.processAnnotation() fills in the methode applyConstraint()
the AccessStrategy with Class<?> therefore Parameters of methodes with Generics won't
find a Validator to validate them.
> You will get an exception:
> Caused by: javax.validation.UnexpectedTypeException: No validator could be found for
type java.util.Map. See: @NotEmpty at org.apache.bval.jsr303.extensions.ParameterAccess@1d2f117
> The parameter of the my method is Map<Object, Object>.
> I have attached a patch-file.
> I don't know i this is the best way to solve the problem or if there is allready a patch
or i use the validation in a wrong way.
> Thank you.
