+ * Usage:

+ *   2. hotspot_calls_tree.d -p JAVA_PID
+ *
+ * This script prints calls tree of fired 'hotspot' probes.
+ *
+ * Notes: 
+ *    The script uses 'monitors' probes which are disabled by default since
+ *    it incurs performance overhead to the application. To enable them, you
+ *    need to turn on the ExtendedDTraceProbes VM option. You can either
+ *    start the application with -XX:+ExtendedDTraceProbes option or use the
+ *    jinfo command to enable it at runtime as follows:
+ *
+ *       jinfo -flag +ExtendedDTraceProbes <java_pid>
