I think this test was written for JEP341 where it eliminates and extra step of doing `-Xshare:dump` and enables `-Xshare:auto` by default. At that time, there was only one CDS archive (classes.jsa). It gets more complicated now with the COH option. I'm fine with removing this test. If the "default" archive is not available for some reasons, other tests such as the  dynamic CDS archive tests would fail so we have coverage there.
