- * @author Eamonn Mcmanus

-/**
- * The idea is that we will create a hierarchy like this:
- * a//
- * X
- * b//
- * Y
- * Z
- * and we will use MXBean references so we have links like this:
- * a//
- * X----+
- * b// |
- * /
- * Y
- * \
- * /
- * Z
- * In other words, X.getY() will return a proxy for Y, which the MXBean
- * framework will map to b//Y. A proxy for a//X should then map this
- * into a proxy for a//b//Y. That's easy. But then if we call getZ()
- * on this proxy, the MXBean framework will return just Z, and the proxy
- * must map that into a proxy for a//b//Z.
