Which SVN revision? Which environment?

[alin.heyoulin.qq.com]

Temporary add a patch:

In org.jboss.weld.introspector.jlr.AbstractWeldAnnotated.java

chage

public Class<T> getJavaClass()
   {
      return (Class<T>) (rawType==null?Object.class:rawType);
   }


Now it works.


hava any idea?

[alin.heyoulin.qq.com]

rev 5658. It's the newest vision. Using rev 5655 work fine.

I use tomcat 6.0.18 and seam remoting 3.0.

Just deploy like that class in seam remoting 3.0:

public class GJDepthFirst<R,A> implements GJVisitor<R,A> {
   //
   // Auto class visitors--probably don't need to be overridden.
   //
   public R visit(NodeList n, A argu) {
      R _ret=null;
      int _count=0;
      for ( Enumeration<Node> e = n.elements(); e.hasMoreElements(); ) {
         e.nextElement().accept(this,argu);
         _count++;
      }
      return _ret;
   }

     ..........

I dig into source and find that:


WeldParameter<?, X> parameter = WeldParameterImpl.of(annotatedParameter.getAnnotations(), Reflections.getRawType(annotatedParameter.getBaseType()), annotatedParameter.getBaseType(), this, annotatedParameter.getPosition(), classTransformer);


Reflections.getRawType(annotatedParameter.getBaseType()) will return null for paramater (A argu)

Thanks, I also found the bug during testing, now fixed :-)
