and now getting

in one of my projects, I'm currently not able to isolate this as a test-case.

It seems to be triggered by the usage of the following component property type:

@Retention(CLASS)
@Target(TYPE)
@ComponentPropertyType
public @interface HttpMethod {

	Verb value();
}

With this enum

public enum Verb {
	GET, POST;
}

then used in a component:

@HttpMethod(Verb.GET)
@Component
public class MyComponent {

}
