`java.util.Properties` defines the `loadFromXML` and `storeToXML` methods for `Properties` stored in XML documents. XML specifications only require XML processors to read entities in UTF-8 and UTF-16 and the API docs for these methods only require an implementation to support UTF-8 and UTF-16. The implementation of these methods has changed in JDK 9 to use a smaller XML parser which may impact applications that have been using these methods with other encodings. The new implementation does not support all encodings that the legacy implementation had support for, in particular it does not support UTF-32/UCS-4, IBM* or x-IBM-* encodings. For maximum portability, applications are encouraged to use UTF-8 and UTF-16.
