I absolutely agree that for a vast majority of the cases this is a design issue, and the problem will be fixed with a different (and better) design.

My point simply was that there may be a scenario where the design cannot be changed (for some reason). I’ve tried to highlight a solution that would work for such a particular case.

You can do this in Eclipse AFAIK. I’ve run into this issue before with SUN’s compiler which does not allow simple modeling of a state machine using Enum (through vararg constructor):

PlayerState.PLAY(STOP, PAUSE), PlayerState.STOP(PLAY),…

It seems like in this code Resource is actually a ResourceContainer – that looks suspecious and may suggest that different design could solve the problem.

I think that this is more of design problem than Java issue – why would you need such a dependency? Can’t you resolve it by using other objects?

In essence you are trying to something like that:

public static final String A = new String(B);
public static final String B = new String(C);
public static final String C = new String(A);
