Method javax.swing.JLayer.remove(Component comp) overrides method in java.awt.Container and inherits its specification.

However it's behavior is tuned a little:

    public void remove(Component comp) {
        if (comp == getView()) {
            setView(null);
        } else if (comp == getGlassPane()) {
            setGlassPane(null);
        } else {
            super.remove(comp);
        }
    }

This logic migth deserve to be specified.

Also, the same applies to :

    /**
     * {@inheritDoc}
     */
    public void removeAll() {
        setView(null);
        setGlassPane(null);
    }
The following JCK tests verify this behavior:
