This is an old question, but still, I couldn't find an acceptable answer for my situation. Basically, Java doesn't have a built-in encoder for UTF-16LE with a BOM. And so, you have to roll out your own implementation.

Here's what I ended up with:

private byte[] encodeUTF16LEWithBOM(final String s) {
    ByteBuffer content = Charset.forName("UTF-16LE").encode(s);
    byte[] bom = { (byte) 0xff, (byte) 0xfe };
    return ByteBuffer.allocate(content.capacity() + bom.length).put(bom).put(content).array();
}
