> I have a simple servlet that calls some BV apis, like this:
> {code}
>         List<String> listOfString = new ArrayList<String>();
>         listOfString.add("one");
>         listOfString.add("two");
>         listOfString.add("three");
>         Set<ConstraintViolation<Person>> violations =
>                 beanValidator.validateValue(Person.class, "listOfString", listOfString);
> {code}
> However, when the _validateValue()_ call is made a _java.security.AccessControlException_ exception is thrown.  
> The code throwing the exception is 
> {code}
> org.hibernate.validator.metadata.ConstraintDescriptorImpl.equals(ConstraintDescriptorImpl.java:289).
> {code}
> The code looks innocent enough:
> {code}
> 	@Override
> 	public boolean equals(Object o) {
> 		if ( this == o ) {
> 			return true;
> 		}
> 		if ( o == null || getClass() != o.getClass() ) {
> 			return false;
> 		}
> 		ConstraintDescriptorImpl<?> that = (ConstraintDescriptorImpl<?>) o;
> 		if ( annotation != null ? !annotation.equals( that.annotation ) : that.annotation != null ) {
> 			return false;
> 		}
> 		return true;
> 	}
> {code}
> The exception is thrown on the invocation of _annotation.equals()_, as
> shown in this stack trace:
> {noformat}
