How do I know if my components are lightweight?

I'm trying to verify that I'm using lightweight components/containers.I see that my container's peer is sun.awt.NullComponentPeer.Does that mean that it's a lightweight component?Thanks.

AWT components are heavy, Swing components are light. Does that answer your question?
