     * This method is called when invoke doesn't find the named method.
     * Before throwing an exception, we check to see whether the
     * jmx.invoke.getters property is set, and if so whether the method
     * being invoked might be a getter or a setter.  If so we invoke it
     * and return the result.  This is for compatibility
     * with code based on JMX RI 1.0 or 1.1 which allowed invoking getters
     * and setters.  It is *not* recommended that new code use this feature.
     *
     * Since this method is either going to throw an exception or use
     * functionality that is strongly discouraged, we consider that its
     * performance is not very important.
     *
     * A simpler way to implement the functionality would be to add the getters
     * and setters to the operations map when jmx.invoke.getters is set.
     * However, that means that the property is consulted when an MBean
     * interface is being introspected and not thereafter.  Previously,
     * the property was consulted on every invocation.  So this simpler
     * implementation could potentially break code that sets and unsets
     * the property at different times.
