How do I translate text in .java source files?

I have an enum like this

public enum CheckboxFeature {

    Option1(" choose this"),
    Option2(" or this"),
    Option3(" maybe this"),
    Option4(" lastly this");

    @Getter
    private final String text;

    public static CheckboxFeature fromName(String v) {
        for (CheckboxFeature c: CheckboxFeature.values()) {
            if (c.name().equalsIgnoreCase(v)) {
                return c;
            }
        }
        throw new IllegalArgumentException(v);
    }
}

This shows the four options as checkboxes in the web view

<form:checkboxes items="${features}" path="enabledFeatures" itemLabel="text" delimiter="<br/>"/>

How can I translate these options? I use fmt:message for the rest of the translations in the web view.

I have tried 

Option1(" <fmt:message key=\"text.test\"/>"),

and 

Option1(" ${option1}"),

with 

<fmt:message key="text.select" var="option1"/>

in the .jsp. Neither of them work, so it seems it can't work this way. What is the correct way of translating the strings? Ideally using the fmt:message and i18n resources (lang.properties files) that are in place and working on the rest of the servlet?

Optimally, you get the resource key from the enum, and look that up.

public enum CheckboxFeature {
    Option1("label.option1.key"),
    Option2("label.option2.key"),
    Option1("label.option3.key"),
    Option2("label.option4.key");

    private final String key;
    [...]

I don't know how to nest a l10n lookup in the itemLabel attribute, so I would write something like:

<c:forEach items="Options.values()" var="current">
    <form:checkbox path="selectedOptions" value="${current.name()}"/> <fmt:message key="${current.getKey()}"/>
</c:forEach>

1、CheckboxFeature add method like:

 public static List<String> getAllCheckboxFeature(String v) {
        return Arrays.asList(Option1.getText(),...Option4.getText());
 }


2、than use the jstl like:

<c:forEach items="${options}" var="option">
    <input type="checkbox" ="${option}">
</c:forEach>
