Hello,<br>
<br>
I'm looking for a couple of reviews of the change extending the
WhiteBox API to retrieve information about <br>
supported collectors and how the collector was selected.<br>
<br>
<a class="moz-txt-link-freetext" href="https://bugs.openjdk.java.net/browse/JDK-8154096">https://bugs.openjdk.java.net/browse/JDK-8154096</a><br>

<br>
This change is required to improve work of the jtreg @requires. Now
jtreg sets vm.gc property <br>
based on the given flags (matching VM options for -XX:+Use???GC
pattern). The extended WhitBox API <br>
will allow us to set properties like:<br>
vm.supportsSerialGC<br>
vm.supportsParallelGC<br>
vm.supportsConcMarkSweeGC<br>
vm.supportsG1GC<br>
<br>
And use in test more reliable expression:<br>
@requires vm.supportsG1GC <br>
instead of <br>
@requires vm.gc == null | vm.gc == "G1" <br>
<br>
The following CRs are blocked by this RFE.<br>

Tested locally.<br>
