I'm not sure how MapContext work (I'm not familiar with this part). But=20
the underyling renderer use the z-order hint for determining the order.=20
This hint can be set with RenderedLayer.setZOrder(z). I guess that=20
setting the same z value than the old layer (as returned by=20
RenderedLayer.getZValue()) should do the trick.

I'm in the process right now to rewrite the renderer as a GO-1=20
implementation (the org.opengis.go packages there:=20
http://geoapi.sourceforge.net/2.0/javadoc/index.html). It make take a=20
few months before it become ready, but I hope to fix many J2D renderer=20
issues in this process.
