validation jboss wildfly bean-validation wildfly-8

Type interface org.hibernate.validator.method.MethodValidator not supported for unwrapping

I'm using JSR 303 Bean validation on my RestEasy endpoints:

@Path("/")
@Produces(MediaType.APPLICATION_JSON)
@ValidateRequest
public class RecipeEndpoint
{
    //more code

    @GET
    @Path("/get/{accessId}")
    @Consumes(MediaType.TEXT_PLAIN)
    public Response getByAccessId(@PathParam("accessId") @NotEmpty String accessId) throws InternalServerErrorException
    {
        RecipeBo result = recipeService.getByAccessId(accessId, userId);

        return Response.ok().entity(result).build();
    }
}

when I startup Wildfly 8.2.0.Final I get the following exception:

At first I though it depends on the first WARN and found this entry: https://issues.jboss.org/browse/WFLY-3812 I checked the solution but in /opt/wildfly/modules/system/layers/base/org/picketlink/core/main/module.xml there are these dependencies:

<module name="org.jboss.weld.core"/>
<module name="org.jboss.weld.spi"/>

Maybe it has no effect or it does not even affect the validation WARN:

Type interface org.hibernate.validator.method.MethodValidator not supported for unwrapping.

I didn't add any own implementations of any Validator. Do I miss anything here to get bean validation to work?

Solution

It really smells like a classloading issue. You should make sure you do not package any of the provided EE dependencies in your war/ear archive (resteasy-hibernatevalidator, hibernate-, weld-).
