/**
* When a {@link java.lang.SecurityManager SecurityManager} set, this
* is the permission which will be checked when code invokes {@link
* VirtualMachine#attach VirtalMachine.attach} to attach to a target virtual
* machine.
* This permission is also checked when an {@link
* com.sun.tools.attach.spi.AttachProvider AttachProvider} is created. </p>
*
* <p> An <code>AttachPermission</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.
* 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>attachVirtualMachine</td>
* <td>Ability to attach to another Java virtual machine and load agents
* into that VM.
* </td>
* <td>This allows an attacker to control the target VM which can potentially
* cause it to misbehave.
* </td>
* </tr>
*
* <tr>
* <td>createAttachProvider</td>
* <td>Ability to create an <code>AttachProvider</code> instance.
* </td>
* <td>This allows an attacker to create an AttachProvider which can
* potentially be used to attach to other Java virtual machines.
* </td>
* </tr>
*
* </table>
* <p>
* Programmers do not normally create AttachPermission objects directly.
* Instead they are created by the security policy code based on reading
* the security policy file.
