In JBC 1.x, TreeCache inherits field serviceName from superclass ServiceMBeanSupport. That field stores the name the service was registered under when the JMX server calls ServiceMBeanSupport.preRegister(MBeanServer, ObjectName). And it seems MBeanConfigurator.registerInterceptors() is properly using that field. So it's odd that there is a mismatch.
