Issue:
Flaky 2FA test TwoFactorControllerTest.testEnrollTOTP2FA , gives no stacktrace when it fails.
This is the only output we get when it fails:
And
com.google.zxing.ChecksumException
Cause:
Seems to be the QR decode method can fail sometimes, due to lack of precision in the decoder.
There is a choice between performance/speed and accuracy in the decoder, and the default settings prefer speed.
Fix:
Tell the decoder to prefer accuracy.
