> The javax.jws.WebService in jbossws14-client.jar breaks Class#isAnnotationPresent().
> Because the javax.jws.WebService annotation is defined to extend org.jboss.lang.Annotation, instead of java.lang.annotation.Annotation, the Java language method Class#isAnnotationPresent() throws a ClassCastException when it tries to cast JBoss' javax.jws.WebService to a java.lang.annotation.Annotation in sun.reflect.annotation.AnnotationParser#annotationForMap().
> To replicate:
> Create a class, MyService:
> package test;
> import javax.jws.WebService;
> @WebService
> public class MyService {
> 	public void execute() {
> 		
> 	}
> }
> Create a class, TestAnnotation:
> package test;
> import javax.jws.WebService;
> public class TestAnnotation {
> 	public static void main(String[] args) {
> 		Class clazz = MyService.class;
> 		boolean hasAnnotation = clazz.isAnnotationPresent(WebService.class);
> 		System.out.print("Has annotation? " + hasAnnotation);
> 	}
> }
> Run TestAnnotation against the jbossws14-client.jar (and its dependencies). The following exception will be thrown:
> Exception in thread "main" java.lang.ClassCastException: $Proxy0
> 	at sun.reflect.annotation.AnnotationParser.annotationForMap(Unknown Source)
> 	at sun.reflect.annotation.AnnotationParser.parseAnnotation(Unknown Source)
> 	at sun.reflect.annotation.AnnotationParser.parseAnnotations2(Unknown Source)
> 	at sun.reflect.annotation.AnnotationParser.parseAnnotations(Unknown Source)
> 	at java.lang.Class.initAnnotationsIfNecessary(Unknown Source)
> 	at java.lang.Class.getAnnotation(Unknown Source)
> 	at java.lang.Class.isAnnotationPresent(Unknown Source)
> 	at test.TestAnnotation.main(TestAnnotation.java:8)
> The JSR-181 APIs provided by jbossws14-client.jar should not extend JBoss custom classes, I don't think. Especially not something as fundamental as Annotation.
> Respectfully,
> Brice Ruth
