      If you have created the default CDS archive by "java -Xshare:dump", then " java -XX:+EnableValhalla -version" would fail with a stack trace similar to the following. That's because CDS is automatically used when the default archive exists.

      Because Valhalla does not support CDS yet, the VM should automatically disable CDS when -XX:+EnableValhalla is specified.
