.SH NAME
j_flowtime.d - snoop Java execution with method flow and delta times.
.SH SYNOPSIS

.SH DESCRIPTION
This traces activity from all Java processes on the system with hotspot
provider support (1.6.0) and the flag "+ExtendedDTraceProbes". eg,
java -XX:+ExtendedDTraceProbes classfile

This watches Java method entries and returns, and indents child
method calls.
.SH OS

.SH WARNING
Watch the first column carefully, it prints the CPU-id. If it
changes, then it is very likely that the output has been shuffled.
Changes in TID will appear to shuffle output, as we change from one thread
depth to the next. See Docs/Notes/ALLjavaflow.txt for additional notes.

.SH DOCUMENTATION
See the DTraceToolkit for further documentation under the 
Examples, Notes and Docs directories. The example files may be
especially useful as they aim to demonstrate how to interpret
the output.
