Generic forwarding methods with recursive bounds.

Question

Hello all,
I'm attempting to create a forwarding class assoicated with an interface. The interface has a generic method with recursive bounds. The problem relates to ambiguous method calls as the following code segment should demonstrate:
interface TestInterface
    //generic method with recursive bounds. (use of Comparable<T> is
    // not relevant, any generic class/interface could have been used.)
    <T extends Comparable<T>> T testMethod(T bob);
//Concrete implementation of the TestInterface.
class TestClass implements TestInterface
    public <T extends Comparable<T>> T testMethod(T bob)
       return bob;
    public static void main(String[] args)
        TestInterface bob = new TestClass();
        bob.testMethod("blah"); //Works fine.
class ForwardingClass implements TestInterface
    //Forwarding class composed of a TestClass object. All methods forward calls to this object.
    private final TestClass test;
    public ForwardingClass(TestClass test)
        this.test = test;
    //forwarding method.
    public <T extends Comparable<T>> T testMethod(T bob)
        return test.testMethod(bob);   //Ambiguous testMethod call. Both testMethod (T) in TestClass
                                       //and testMethod (T) in TestInterface match. Very annoying...
    }Therefore, if you could assist with the following issues, it would be greatly appreciated.
Firstly, I don't think I fully understand why this error is given, so any explanation would be greatly appreciated.
Secondly, is there any way to get around the problem?
Thanks in advance,
Matt.

My bad. This appears to be an issue with Intellij 8.0M1. I'll create post on the Intellij forums. It compiles absolutely fine from the command line, and using Intellij 7.04. (Probably should have checked that before my initial post...)
Apologies for wasting your time. Cheers for the replies.
Matt.
