FULL PRODUCT VERSION :
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
I have a generic interface that defines a getter method that uses the generic type.

When I Introspect a a class that implements this method, the Propertydescriptor for the method claims that the property type is Object when it should return the actual type declared in the class.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run the test case:

javac NameBean.java
java NamedBean


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expected to see:
Property class: class java.lang.Class
Property name: class java.lang.String

Which is what I get if I compile and run using :
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing)
ACTUAL -
What I get is:
Property class: class java.lang.Class
Property name: class java.lang.Object

I also get the same result when I run this with the latest build:
java version "1.6.0_01-ea"
Java(TM) SE Runtime Environment (build 1.6.0_01-ea-b03)
Java HotSpot(TM) Client VM (build 1.6.0_01-ea-b03, mixed mode)

REPRODUCIBILITY :
This bug can be reproduced always.
