ValuedListProperty extends ValuedProperty<List<T>> { @Override public boolean isCommaSeparated() { return true; } ValuedListProperty(@NotNull final String key, @NotNull final ValueParser<List<T>> valueParser, final List<T> defaultValue); @Override boolean isCommaSeparated(); @Nullable @Override String describeDefault();  }### Answer:
