> This happens, if the AP examines a constraint annotation, which is not defined in the currently built project itself, but is imported from some other JAR (e.g. @Length from HV):
> public class TestModel {
> 	@Length
> 	private String test;
> }
> The problem occurs, regardless whether the JAR containing the constraint is on the AP classpath or not.
> The AP works as expected when running on javac.
