[jbossws-issues] [JBoss JIRA] Updated: (JBWS-1577) javax.jws.WebService in jbossws14-client.jar breaks Class#isAnnotationPresent()

javax.jws.WebService in jbossws14-client.jar breaks Class#isAnnotationPresent() ------------------------------------------------------------------------------- Key: JBWS-1577 URL: http://jira.jboss.com/jira/browse/JBWS-1577 Project: JBoss Web Services Issue Type: Bug Security Level: Public(Everyone can see) Components: jbossws Environment: n/a Reporter: Brice Ruth Assigned To: Thomas Diesler 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
