/**
 * Encountered Class linkage problems in somce ClassLoaders --
 * such as the one used with the Swing and AWT views of JUnit (JUnit's
 * text-based view was fine, since it doesn't use the same CL) and
 * some versions of Tomcat -- that are compounded by extraneous
 * loader context switching in the JMX RI. This ClassLoader does
 * nothing other than insist that MBeans are loaded by a specific
 * loader in order to avoid linkage problems between contexts.
