RFR: JDK-8134373: explore potential uses of convenience factories within the JDK

[Andrej Golovnin]

Hi Jonathan,

src/java.base/share/classes/java/util/ResourceBundle.java

2490     public static class Control {
2491         /**
2492          * The default format <code>List</code>, which contains the strings
2493          * <code>"java.class"</code> and <code>"java.properties"</code>, in
2494          * this order. This <code>List</code> is {@linkplain
2495          * Collections#unmodifiableList(List) unmodifiable}.
2496          *
2497          * @see #getFormats(String)
2498          */
2499         public static final List<String> FORMAT_DEFAULT =
List.of("java.class", "java.properties");

I think you should also change the JavaDocs in the
ResourceBundle.Control class for the constants FORMAT_CLASS,
FORMAT_DEFAULT and FORMAT_PROPERTIES, because the JavaDocs for this
constants explicitly mentions, that the lists are created by using
Collections#unmodifiableList(List). Or you cannot change this
constants at all because they are part of the Public API and existed
in this form for a long time. Please ask someone from Oracle for help.
They can explain it better when it is OK to change and when not. Maybe
Stuart can do that.

Best regards,
