This log is repeated for as long as the application is looking for QR-codes.

Start by reproducing the failure from the Mobilepay QR-code scan entry point on the reported Android setup. Review the repeated barcode-module and unsupported-class-loader log messages to identify where scanning stops. Done means the KBC Mobile flow recognizes a visible QR code and displays its payment information.
