AnnotatedElementMetaDataLoader and bridge methods

[wolfc]

Given a bean with a bridge method I don't get the annotations of the real method if I pass in a bridge method signature to AnnotatedElementMetaDataLoad.getComponentMetaDataRetrieval.

Either it should just work or it should throw an IllegalArgumentException at some point.

See attached patch for a test case.

I've made AnnotatedElementMetaDataLoader attempt to find a matching method. If it cannot be found, a null element loader is returned (or maybe I should throw an exception instead?)

Just so I remember in case I need to come back to it, this simple test

public class BridgeMethodTest
{
   static class BaseGenerics<T>
   {
      T getThing(T t)
      {
         return t;
      }
   }

   static class ChildGenerics extends BaseGenerics<String>
   {
      String getThing(String s)
      {
         return s;
      }
   }

   public static void main(String[] args)
   {
      for (Method m : ChildGenerics.class.getDeclaredMethods())
         System.out.println(m + " - " + m.isBridge());
   }
}

gives

java.lang.String org.jboss.test.benchmark.BridgeMethodTest$ChildGenerics.getThing(java.lang.String) - false
java.lang.Object org.jboss.test.benchmark.BridgeMethodTest$ChildGenerics.getThing(java.lang.Object) - true

The only reason I can think of for throwing an exception would be speed. It's considerably slower when a bridge method is passed in.

Then again the problem would move to the proxy, so I don't see a way to gain.
