> Using `TikaEncodingDetector.guessEncoding` may result in an `ArrayIndexOutOfBoundsException`.
>  
> The following snippet:
> {noformat}
> String encoding = new TikaEncodingDetector().guessEncoding(new URL("https://www.streetpadel.com/overgrip-head-pro-grip-dz-negro-p-17233.html").openStream());
> System.out.println(encoding);{noformat}
> Will result in the following exception:
> {noformat}
> Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 32768Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 32768 at org.jsoup.parser.CharacterReader.consume(CharacterReader.java:100) at org.jsoup.parser.TokeniserState$34.read(TokeniserState.java:556) at org.jsoup.parser.Tokeniser.read(Tokeniser.java:57) at org.jsoup.parser.TreeBuilder.runParser(TreeBuilder.java:64) at org.jsoup.parser.HtmlTreeBuilder.parseFragment(HtmlTreeBuilder.java:126) at org.jsoup.parser.Parser.parseFragment(Parser.java:140) at org.apache.any23.encoding.TikaEncodingDetector.parseFragment(TikaEncodingDetector.java:184) at org.apache.any23.encoding.TikaEncodingDetector.guessEncoding(TikaEncodingDetector.java:95) at org.apache.any23.encoding.TikaEncodingDetector.guessEncoding(TikaEncodingDetector.java:159) at org.apache.any23.encoding.TikaEncodingDetector.guessEncoding(TikaEncodingDetector.java:58){noformat}
> Whereas the expected result is `ISO-8859-15`
> Note the bunch of HTML at the bottom of the page after the `</html>` tag.
>  
> Replacing:
> {code:java}
> ParseErrorList htmlErrors = ParseErrorList.tracking(Integer.MAX_VALUE);
> {code}
> By:
> {code:java}
> ParseErrorList htmlErrors = ParseErrorList.tracking(100);
> {code}
>  
> Will fix the issue. Not quite sure why, maybe at one point the errors are too far and the reader cannot reset far enough...
