Hello Jon,<br>
<br>
I have added a testcase to test the VerifySubSet option:<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://cr.openjdk.java.net/%7Epoonam/8072725/webrev.01/">http://cr.openjdk.java.net/~poonam/8072725/webrev.01/</a><br>
<br>
Here, I run the test with one set of VerifySubSet options, and
then check the output that those sub-systems were verified and the
ones not specified were not verified.<br>

<br>
Excellent. Thanks for adding the test.<br>

Some of the string list parameters allow separation by ,
or " ". Did<br>
you consider adding that?<br>
<br>

<font face="Times New Roman, Times, serif">The </font>VerifySubSet
string list can accept the strings separated by comma or a
space. Before verification, we just need to check if a
particular subset is present in the VerifySubSet list or not.
We don't need any complicated processing of the strings list
here.<br>

<br>
Ok. Thanks for the explanation.<br>
<br>
You mention in the RFR that you have a simple test to test the<br>
change. Can you add that as a jtreg test? I'm thinking about<br>
something like<br>
<br>
test/gc/TestVerifyDuringStartup.java<br>
test/gc/TestVerifySilently.java<br>

Hello,<br>
<br>
Please review these changes that split up the work done
under Verify*GC options. This will be very useful in
debugging GC issues/crashes where verifying the whole
memory system with Verify*GC options slows down the
process and makes it impossible to reproduce the problem.<br>
<br>
The changes introduce a new option <i>VerifySubSet</i><i>
</i>that can be used to specify the specific memory
sub-systems that one wants to verify. It can be one or
more of the sub-systems from these: threads, heap,
symbol_table, string_table, codecache, dictionary,
classloader_data_graph, metaspace, jni_handles, c-heap
and codecache_oops. If nothing is specified with <i>VerifySubSet</i>
then whole of the memory system is verified with Verify*GC
options.<br>
