* Usage:
* 1. hotspot_calls_tree.d -c "java ..."
* 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>
