Sorry about that - wrote the test case directly into JIRA based on a rather more complex case. Here's stuff that compiles and the associated stack-trace.

SampleService.java

package test;

import javax.validation.constraints.NotNull;

public interface SampleService {
    @NotNull
    String getGreeting(@NotNull String greetee);
}

SampleServiceImpl.java

package test;

import javax.validation.constraints.NotNull;

public class SampleServiceImpl implements SampleService {
    @NotNull
    private String greeting;

    public void setGreeting(String greeting) {
        this.greeting = greeting;
    }

    @Override
    public String getGreeting(String greetee) {
        return greeting + " " + greetee;
    }
}

HibernateValidatorIssueTest.java

package test;

import javax.validation.Validation;
import javax.validation.Validator;
import org.hibernate.validator.HibernateValidator;
import org.junit.Test;

public class HibernateValidatorIssueTest {
    @Test
    public void testHibernateIssue() {
        Validator validator = Validation.byProvider(HibernateValidator.class)
            .configure()
            .buildValidatorFactory()
            .getValidator();

        SampleServiceImpl sampleService = new SampleServiceImpl();
        sampleService.setGreeting("Hello");

        validator.validate(sampleService);
    }
}

The stack trace is:
