/**
 * A tricky MBean server builder which produces an mbean server
 * with id "TckMBeanServer" for any requested server. The platform
 * MBean server becomes available under this name, too, which allows
 * as to pass JCache TCK version 1.0 and hopefully TCK version 1.1.

 * <p>Ideally this class is redundant for TCK version 1.1 onwards.
