    Description

      method-entry/return, object-alloc, and monitor-entry/exit probes are disabled by fault in the Mustang VM. The users are required to set -XX:+ExtendedDTraceProbes at startup time so that these probes can be enabled by DTrace at runtime.

      One most important and powerful feature DTrace provides is the ability to trace applications without requiring it to restart (with special flags). So we should fix this so that these probes can be turned on any time.
