31 * A class loader proxy able to serialize simple POJOs between two class
32 * loaders. It only works for simple POJOs following the Java Beans semantics.
33 * The local and remote classes do not have to match or even be derived from
34 * each other as long as their properties match. Any bean properties that the
35 * source bean exposes but the target bean does not will silently be ignored.
