Currently, the applications/jcstress tests report failure 'java.lang.Error: TESTBUG: Can not resolve artifacts for applications.jcstress.JcstressRunner' when there is no args '-Djdk.test.lib.artifacts.jcstress-tests-all=jcstress-latest.jar' pass to jtreg.
In this situation, I think throw jtreg.SkippedException is more elegant than report test failure.

Blow is the test log snippet:
