Thanks for the review.<br>

The delta webrev with you suggestion to use OutputAnalyzer
shouldMatch is<br>
here<br>

<br>
I used my own Matcher in cases where I wanted to extract more
information<br>
after I had a match.<br>
<br>
Full webrev is<br>

I've updated the 01 version. The test has not changed.<br>
Thanks again for catching that.<br>

Nice catch! Your change looks good. <br>
<br>
The method WorkerDataArray<T>::sum(uint
active_threads) just above the average() method
has the same issue. Can you fix that too? <br>
</blockquote>
<br>
</span> Yes, indeed.<br>
<br>
I messed up the delta a bit so all the changes are in
the workerDataArray.inline.hpp<br>
webrev. The test has not changed.<br>

The code changes look good. (I realize that the sum() iteration
was actually correct, but I your changes are much easier to read.)<br>
<br>
The test could be simplified a bit if you use the shouldMatch()
method on the OutputAnalyzer rather than compiling your own
regexps.<br>
<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://hg.openjdk.java.net/jdk9/hs-rt/hotspot/file/9037ef388634/test/testlibrary/jdk/test/lib/OutputAnalyzer.java#l224">http://hg.openjdk.java.net/jdk9/hs-rt/hotspot/file/9037ef388634/test/testlibrary/jdk/test/lib/OutputAnalyzer.java#l224</a>
<br>
<br>
You already have an instance of OutputAnalyzer in your test:<br>
<br>
<br>
64 OutputAnalyzer output = new
OutputAnalyzer(pb.start());<br>
<br>
So, this:<br>
<br>
<br>
70 String parallel_phase_leader = "Evacuate Collection
Set: \\d+\\.\\d+ms";<br>
71 String std_out = output.getStdout();<br>
72 Matcher m = Pattern.compile(parallel_phase_leader,
Pattern.MULTILINE).matcher(std_out);<br>
73 <br>
74 if (!m.find()) {<br>
75 throw new Exception("Could not find correct output
for Evacuate Collection Set: in stdout," +<br>
76 " should match the pattern \"" +
parallel_phase_leader + "\", but stdout is \n" +
output.getStdout());<br>
77 } else {<br>
<br>
Could be replaced by the single line:<br>
<br>
output.shouldMatch("Evacuate Collection Set: \\d+\\.\\d+ms");<br>
<br>
Similarly for the other matching in the test.<br>
<br>
