Matt Benson commented on BVAL-95:
---------------------------------
There is a sandbox "pseudo-branch" of bval at
svn.apache.org/viewvc/incubator/bval/sandbox/lang3-work/ , which uses some type
handling code from the forthcoming release of commons-lang 3.0 to improve the
generics handling throughout the bval codebase. Your test seems to work for me
using that code, so this issue should be fixed in due time.

> 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.
