JavaChecker2

gwt include defintion of annotation inside interface.

public interface Constants extends LocalizableResource {
/** * Default boolean value to be used if no translation is found (and also used as the * source for translation). No quoting (other than normal Java string quoting) * is done.
*/
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
@Documented
public @interface DefaultBooleanValue {
boolean value();
}

I'm not sure is this legal java (need to check) and add support for this (which is not hard)
