• Since the behavior for large IDs now returns UNKNOWN_ID, consider adding a test case that explicitly verifies ParserUtil.parseSessionId returns Session.UNKNOWN_ID for inputs exceeding Integer.MAX_VALUE.

assertThrows(ParseException.class, Session.MESSAGE_INVALID_ID, () -> ParserUtil.parseSessionId(Long.toString(Integer.MAX_VALUE + 1)));
