/**
 * 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 AttachPermission 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.

 * permission.
