/**
This Interceptor wraps the real MBeanServer so that additional interceptor code can be
"turned on" at a later point. However, it must be possible to start the MBeanServer even before
the JVM calls main(). Therefore,
<b>This class must not depend on anything that can't initialize before the JVM calls main().
<i>This includes things like logging which is not happy being invoked
that early.</i>
<p>
When instantiated at startup, the instance of this class that wraps the real MBeanServer
is termed the "Primary Interceptor". There can only be one such Interceptor for each
*real* MBeanServer. MBeanServer #0 is the Platform MBeanServer, and this class <b>must be
used for GlassFish. Additional MBeanServers can be created if desired.
<p>
This class can also be used to implement an Interceptor which can be set for use by the Primary
Interceptor. Such interceptors are used only for get/setAttribute(s) and invoke(), though
the use of them could be expanded for other methods.
<p>
Note that many methods are declared 'final' for efficiency. If a subclass needs
to override a method, remove 'final'. Until that time, we might as well remain efficient,
since most methods won't be overridden.
