I think you can do this to keep the checks on lines 130 .. 131:


            .addSuffix("-showversion", mainClass);
        OutputAnalyzer output = CDSTestUtils.runWithArchive(runOpts);
        if (output.getStderr().contains("sharing")) {
            output.shouldMatch(lambdaLoadedFromArchive)
                  .shouldMatch(cdsLoadedLambdaProxy);
        }
