+/**
+ * <p>
+ * Represents the permission to view or modify the data
+ * which forms part of the system management interfaces.
+ * Calls to methods of the system management beans,
+ * provided by the {@link ManagementFactory}, may perform
+ * checks against the current {@link java.lang.SecurityManager}
+ * (if any) before allowing the operation to proceed.
+ * Instances of this object are supplied to the
+ * {@link java.lang.SecurityManager} in order to perform
+ * these checks. It is not normal for instances of this
+ * class to be created outside the use of the
+ * {@link java.lang.SecurityManager}.
+ * </p>
+ * <p>
+ * This object can represent two types of management
+ * permission:
+ * </p>
+ * <ul>
+ * <li><strong>monitor</strong> &mdash; this allows access
+ * to information such as the arguments supplied to the
+ * virtual machine, the currently loaded classes and the
+ * stack traces of running threads. Malicious code may
+ * use this to obtain information about the system and
+ * exploit any vulnerabilities found.</li>
+ * <li><strong>control</strong> &mdash; this allows the
+ * information stored by the management beans to be altered.
+ * For example, additional debugging information (such
+ * as class loading traces) may be turned on or memory
+ * usage limits changed. Malicious code could use
+ * this to alter the behaviour of the system.</li>
+ * </ul>
