I think you need to specify "-jdk:<your_java_home>" option to

In the expanded command line option, ConcGCThread is indeed
set to 1 as expected in the ReclaimRegionFastclass JVM. In
the direct jtreg option, ConcGCThread is 0 in both JVMs. The
usage details are below. My build is based on JDK 9 and I
downloaded the latest jtreg. There may be something wrong in
my jtreg usage -- can you please clarify?<br class="">

This does not look like an issue
with jtreg, since the behavior
you are apparently seeing is all
within the test code and its
libraries.<br class="">
<br class="">
You might want to follow up with
the Hotspot team, who would have
more familiarity with these
tests and the associated
libraries.<br class="">
