Tests:
open/test/jdk/sun/security/pkcs12/KeytoolOpensslInteropTest.java
open/test/jdk/sun/security/provider/acvp/Launcher.java

These tests are throwing SkippedExceptions when they are unable to retrieve artifacts that are available on the artifact server. It might be better if ArtifactResolver throws Exception and the caller considers if the test is marked skipped (i.e., throws SkippedException) or failed.
