Línea de trabajo
Reproduce el fallo con la clase Java proporcionada y, después, inspecciona StringWrapper#applyReplacements y FormatterException#formatDiagnostics. Comprueba el código fuente generado y el tratamiento de la línea de diagnóstico frente a la entrada original. La tarea estará terminada cuando el formateo ya no produzca Java que no se pueda compilar y el formateador informe del error sin IndexOutOfBoundsException.

I ran the main method to ensure it is valid java source code
But when trying to format it using GJF, I got
