Only the first line in a multiline textbox is saved

When creating a custom publisher with a CustomPublisherProperty.UI_TEXTOUTPUT only the first line of the text entered into the multiline textbox is saved.

How can it be fixed best?

The current code in CustomPublisherMBData.java encodes multiple lines as:

Key=Value 1
Value2

I replaced the code with the built in Properties.store method:

public void setCustomPublisherData(final CustomPublisherContainer publisher) throws PublisherException, IOException {
    publisher.setClassPath(customPublisherCurrentClass);
    if (!publisher.isCustomUiRenderingSupported()) {
        publisher.setPropertyData(customPublisherPropertyData);
        return;
    }
    final Properties properties = new Properties();
    properties.putAll(publisher.getCustomUiPropertyList(EjbcaJSFHelper.getBean().getAdmin()).stream()
        .map(p ->  getEntry(p))
        .collect(Collectors.toMap(Entry::getKey, Entry::getValue)));
    final StringWriter writer = new StringWriter();
    properties.store(new PrintWriter(writer), "");
    final String customPublisherDataString = writer.getBuffer().toString();
    log.info("Setting custom publisher data:" + System.lineSeparator() + customPublisherDataString);
    publisher.setPropertyData(customPublisherDataString);
}

private SimpleEntry<?, ?> getEntry(final CustomPublisherProperty p) {
    if (p.getType() == CustomPublisherProperty.UI_TEXTINPUT_PASSWORD &&
        customPublisherPropertyValues.get(p.getName()).equals(PASSWORD_PLACEHOLDER)) {
            return new AbstractMap.SimpleEntry<>(p.getName(), p.getValue());
    } else {
        return new SimpleEntry<>(p.getName(), customPublisherPropertyValues.get(p.getName()));
    }
}

The same data is now saved as:

Key=Value1\r\nValue2

However, it is still not loaded correctly.
