false alert from a check in the annotation processor prevents generation of Koloboke implementation

[robvarga]

The following test case shows the problem (the Koloboke annotation processor incorrectly complains for SubClass when it correctly doesn't complain for Implementor).

package kolobokebug;

import com.koloboke.collect.map.LongObjMap;
import com.koloboke.compile.KolobokeMap;

public class TestCase {
    public interface Iface<P1, P2> {
        P2 methodWithIndependentTypeVariables(P1 p1, P2 p2);
    }
    
    @KolobokeMap
    static abstract class Implementor<P2> implements LongObjMap<Object>, Iface<Integer, P2> {
        @Override
        public P2 methodWithIndependentTypeVariables(Integer p1, P2 p2) {
            return null;
        }
    }
    
    @KolobokeMap
    static abstract class SubClass<V> extends Implementor<V> {
//        @Override
//        public V methodWithIndependentTypeVariables(Integer p1, V p2) {
//            return super.methodWithIndependentTypeVariables(p1, p2);
//        }
    }
}

Interestingly when removing type variable P1 from the method signature, it fixes the problem, so it may be that the problem only happens with methods with a partially bound type defined type variable set.

If we uncomment the redefinition method, it also fixes the problem as then the method is defined in the @KolobokeMap annotated class not a superclass of it, but the whole point of it was to be able to implement these methods only in the super-type of the annotated type.

I used Eclipse for JEE Developers 4.6.1 (whatever it updated itself to), JBoss Maven Integration APT plugin 1.3.0.201610261805
