@Override
public void recover(final LexerNoViableAltException lnvae) {
final CharStream charStream = lnvae.getInputStream();
final int startIndex = lnvae.getStartIndex();
final String text = charStream.getText(Interval.of(startIndex, charStream.index()));

/* Use a simple heuristic to guess if the unrecognized characters were trying to be a string but has a broken escape sequence.
* If it was add an extra message about valid string escape sequences. */
message += " The only valid escape sequences in strings starting with [" + firstChar + "] are [\\\\] and [\\"
+ firstChar + "].";
}
