Java Programming

Hello,

I'm working on a project and with eclipse I can compile my whole project without any problems.
But when I try it manually with javac I get an incompatible types; no instance(s) of type variable(s) error :(

The error message is:

PlayerFactory.java:8: incompatible types; no instance(s) of type variable(s) S exist so that Player<T,S> conforms to Player<T,S>
found : <S>Player<T,S>
required: Player<T,S>
return createRemotePlayer((RemotePlayerInfo)info, termfactory);
1 error

I localize the problem files and delete all contents to show you the problem.

When you try to compile this you get the error:

public abstract class AbstractPlayer<
		T extends TermInterface,
		S extends StateInterface<T,S>
		> implements Player<T,S> {
}

public interface Player<
		T extends TermInterface,
		S extends StateInterface<T,S>
		> {
}

public class RemotePlayer<
		T extends TermInterface,
		S extends StateInterface<T,S>
		> extends AbstractPlayer<T,S> {
}

public interface TermInterface {
}

public interface StateInterface<T extends TermInterface, S extends StateInterface<T,S>> {
}

public class RemotePlayerInfo extends PlayerInfo {
}

public abstract class PlayerInfo {
}


public interface TermFactoryInterface<T extends TermInterface> {
}

public class PlayerFactory {
	public static <T extends TermInterface, S extends StateInterface<T, S>> Player<T,S> createRemotePlayer(RemotePlayerInfo info, TermFactoryInterface<T> termfactory) {
		return new RemotePlayer<T,S>();
	}
	public static <T extends TermInterface, S extends StateInterface<T, S>> Player<T,S> createPlayer(PlayerInfo info, TermFactoryInterface<T> termfactory) {
		if(info instanceof RemotePlayerInfo){
			return createRemotePlayer((RemotePlayerInfo)info, termfactory);
		}
		return null;
	}
}

Do you have an idea where the problem is?

Thank you so much!
