[portlek]

i guess this line is wrong. it should be String.class

default String getString(final String def) { // @cs-: NoGetSetPrefix (not a bean method)
    requireNonNull(def, "def");
    final @Nullable String value = getString();
    if (value != null) {
        return value;
    }
    if (options().shouldCopyDefaults()) {
        Scalars.STRING.serialize(/*This thing*/float.class, def, this);
    }
    return def;
}
