2 tests in particular fail when non-default JVM variant is being tested:
  runtime/SharedArchiveFile/PrintSharedArchiveAndExit.java
  runtime/SharedArchiveFile/NonBootLoaderClasses.java

Proper flags are used when creating CDS archive, but aren't passed to the consequent JVM which tries to load the archive. Wrong JVM is used and archive loading fails due to JVM version mismatch.
