This can be fixed by adding a one-liner to explicitly set the classloader on the elasticsearch Settings class to the classloader of Settings.class:

            Settings settings = ImmutableSettings.settingsBuilder()
                ...
                .classLoader(Settings.class.getClassLoader());
                ...
