I did too until I tried it with Sun's JDK and it behaved identically.

In com.jclark.xml.sax.Driver, there is a method OpenEntity that begins:

private OpenEntity openInputSource(org.xml.sax.InputSource inputSource)
throws IOException {
    Reader reader = inputSource.getCharacterStream();
    String encoding;
    InputStream in;
    if (reader != null) {
      in = new ReaderInputStream(reader);
      encoding = "UTF-16";
    }
    else {
      in = inputSource.getByteStream();
      encoding = inputSource.getEncoding();
    }
    ...

The encoding gets set there and never changes.
