27  /** <P> This is a tag interface (similar to Cloneable) which indicates
28      that the contained address is "special" and is updated under the
29      hood by the VM. The purpose is to support implementation of
30      reflection on the current VM with these interfaces; if the Java
31      code implementing parts of the VM requires proxies for objects in
32      the heap, it must be the case that those proxies are updated if GC
33      occurs. This is the level at which this updating is handled. The
34      VM (and specifically the GC code) must have intimate knowledge of
35      the VM-specific implementation of this interface. </P>
36  
37      <P> Note that in the case of debugging a remote VM, it is not
38      workable to handle the automatic updating of these handles.
39      If the debugger allows the VM to resume running, it will have to
40      look up once again any object references via the path they were
41      found (i.e., the activation on the stack as the root, etc.) </P>
