Long run of periods causes detect() to throw NegativeArraySizeException "Backtracked max amount of characters. Endless loop detected."

String text = ".............:::::::::::;;;;;;;;;;;;;;;::...............................................:::::::::::::::::::::::::::::...................."; UrlDetector d = new UrlDetector(text, UrlDetectorOptions.Default); d.detect();

Running this will throw
Exception in thread "main" java.lang.NegativeArraySizeException: Backtracked max amount of characters. Endless loop detected.

Run the supplied Java reproduction and trace the failing path through InputTextReader.java and UrlDetector.java, starting at detect() and the reported checkBacktrackLoop() call. Done means the input no longer causes NegativeArraySizeException when detect() runs; the issue does not specify the expected detection result.
