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