Looks better. I think we can be less specific in the guidance, see below.

test/hotspot/jtreg/applications/jcstress/README line 34:

Suggestion:

successfully. These tests require a build of org.openjdk.jcstress:jcstress-tests-all.
If this artifact could not be found automatically, you can build it using jcstress
guide[1], and then pass the JAR location with JDK option such as 
-Djdk.test.lib.artifacts.jcstress-tests-all=jcstress-tests-all.jar, 
either with explicit -javaoption: or TEST_VM_OPTS test variable.
