Problems getting generic signatures of generated classes to show via Reflection

(note: apologies if this email gets sent twice -- I had some issues
subscribing to the list)

I am trying to generate simple setters and getters, but such that
return type and arguments would contain proper generic signature. This
is necessary as classes are further introspected by another library
which needs to know generic type information for its handling.
As far as I know, code should work (I have sample later); and when
using ASM's ClassVisitor, things look ok.
However, when trying to access generic type information via reflection
(Class.getDeclaredMethods(), getDeclaredFields()), no generic type
information is seen.
It would seem as if the way ASM adds attributes was somehow not
compatible with regular JDK's expectations.

Code I use is quite simple, along lines of:

---
       final String className = "TestClass";
       final String internalClass = "TestClass";

       ClassWriter cw = new ClassWriter(ClassWriter.COMPUTE_MAXS);

       cw.visit(V1_2, ACC_PUBLIC + ACC_SUPER, internalClass, null,
"java/lang/Object", new String[0]);
       cw.visitSource("TestClass.java", null);

       // default constructor:
       MethodVisitor mv = cw.visitMethod(ACC_PUBLIC, "<init>", "()V",
null, null);
       mv.visitCode();
       mv.visitVarInsn(ALOAD, 0);
       mv.visitMethodInsn(INVOKESPECIAL, "java/lang/Object", "<init>", "()V");
       mv.visitInsn(RETURN);
       mv.visitMaxs(0, 0); // don't care (real values: 1,1)
       mv.visitEnd();

       // one field
       String fieldDesc = "Ljava/util/List;";
       String fieldSig = "Ljava/util/List<Ljava/lang/String;>;";
       final String fieldName = "foo";
       FieldVisitor fv = cw.visitField(ACC_PUBLIC, fieldName,
fieldDesc, fieldSig, null);
       fv.visitEnd();

       // then one getter (removed for now)

       cw.visitEnd();

---

and I even checked with utility class to see what ASM thinks is proper
way to generate classes (using a JDK compiled similar bean as base).
But types that Method and Field show are raw type erased classes.

Any guesses as to what I might be doing wrong?
