Description

Instead of selecting implementation method, bridge method is used. We faced an issue with conversion of parameter when bean implements generic interface.
For example having bean implementation like this:

    public interface Service<R> {

        int process(R request);
    }

    public static class MyService implements Service<Request> {

        public int process(Request request) {
            return request.x + 1;
        }
    }

would lead to beanInfo containing Method with signature

public abstract int process(Object request)

in methodMap

This is not correct as conversion of parameter is not possible in this case.

I could find an issue with the same problem that was previously fixed (CAMEL-8940), but later on it was broken with CAMEL-9656 (commit 5639b78).
