Reproduzieren Sie den Fehler mit der referenzierten Switch.java-Datei und beginnen Sie bei FormatterHandler.format, wobei Sie dem Stack durch DefaultCodeFormatter und TokenManager folgen. Die Arbeit ist abgeschlossen, wenn das Formatieren des Java-String-Template-Beispiels keine IndexOutOfBoundsException mehr auslöst und die im Issue gezeigte erwartete Einrückung erzeugt.
