sortable.
Time
The start time of the event.
Duration
The duration of the event. The event may still be in progress.
Type
The type of the event, one of "waiting" or "blocked".
Monitor ID
The ID of the monitor for identifying multiple events on a particular
monitor instance.
Monitor class
The class of the monitor. If no Java object is associated with this monitor
[raw monitor] is displayed.
Waiting thread

If you profile with Java <=1.4 (JVMPI), the monitor class names can only be displayed if they
are recorded objects. You can enable "Record allocations on startup" in the
