/**
* The <code>JDIPermission</code> class represents access rights to
* the <code>VirtualMachineManager</code>. This is the permission
* which the SecurityManager will check when code that is running with
* a SecurityManager requests access to the VirtualMachineManager, as
* defined in the Java Debug Interface (JDI) for the Java platform.
* <P>
* A <code>JDIPermission</code> object contains a name (also referred
* to as a "target name") but no actions list; you either have the
* named permission or you don't.
* <P>
* The following table provides a summary description of what the
* permission allows, and discusses the risks of granting code the
* permission.
* <P>
* <table border=1 cellpadding=5 summary="Table shows permission
* target name, what the permission allows, and associated risks">
* <tr>
* <th>Permission Target Name</th>
* <th>What the Permission Allows</th>
* <th>Risks of Allowing this Permission</th>
* </tr>
*
* <tr>
* <td>virtualMachineManager</td>
* <td>Ability to inspect and modify the JDI objects in the
* <code>VirtualMachineManager</code>
* </td>
* <td>This allows an attacker to control the
* <code>VirtualMachineManager</code> and cause the system to
* misbehave.
* </td>
* </tr>
*
* </table>
*
* <p>
* Programmers do not normally create JDIPermission objects directly.
* Instead they are created by the security policy code based on reading
* the security policy file.
