The test (and also ClhsdbCDSCore ) use the following to check if CDS is on:

    List<String> cmds = List.of("flags UseSharedSpaces");
    String useSharedSpacesOutput = test.run(theApp.getPid(), cmds,
                                                    null, null);
    ....
    if (!useSharedSpacesOutput.contains("true")) {
        // CDS archive is not mapped. Skip the rest of the test.

But the output looks like this:

    hsdb> hsdb> + verbose true
    hsdb> + flags UseSharedSpaces
    UseSharedSpaces = false command line
    hsdb> + quit

I think at one point the "if" worked, but the "+ verbose true" part of the log must have been added recently to cause the "if" to determine the wrong result.
