/**
Represents the manageable Java Virtual Machine. Various things can be
queried for in this JVM. An MBean correponding to this JVM will be
registered in the MBeanServer. The JVM will be always associated with
a Server Instance or the Admin Server. JVMPI will be used to get
certain management information from a running JVM.
<p>
For iAS SE it is thought that there will be one JVM per Server Instance.
But it should be possible to have multiple JVMs.
<p>
ObjectName of this MBean is:
