Looks like the way the IBM J9 VM looks up annotations is a little different.
Here are my observations of what is happening:
We start trying to determine if a class has the Entity annotation:
org.jboss.seam.Seam.isEntityClass(java.lang.Class<?>) line: 136
if ( clazz.isAnnotationPresent(Entity.class) )
Skipping a few bits of code, but soon enough we end up in the Class
implementation looking for annotations:
public <A extends Annotation> A getAnnotation(Class<A> annotation) {
| if (annotation == null) throw new NullPointerException();
| Annotation[] ans = getAnnotations();
| for (int i = 0; i < ans.length; i++) {
| if (ans.annotationType() == annotation) {
| return (A)ans;
| }
| }
| return null;
| }
Then in the getAnnotations() method:
public Annotation[] getAnnotations() {
| HashMap<String,Annotation> annotations = new
HashMap<String,Annotation>();
| //Store annotations from the current class
| Annotation[] anns = getDeclaredAnnotations();
| ...
|
In getDeclaredAnnotations() it goes all pear-shaped here:
java.lang.Class.getDeclaredAnnotations() line: 1583
annotations = AnnotationHelper.getDeclaredAnnotations(this,
AnnotationHelper.ANNOTATION_TYPE_CLASS, null);
At this point it goes into some internal IBM classes and comes up with this

If our target platform was JBoss this would not be an issue since we can just
use the Sun JDK. However we want to run Seam in Websphere and thus have to use
the IBM JDK.
I reproduced this error in JBoss, just to make clear this is directly related
to the IBM JDK and not Websphere.
