Kotlin: Unwanted "Java HotSpot" warning line in output making the test fail

Hello Team,

when trying to test a solution for the 16x16 Sudoku community problem with Kotlin, the test fails and the output starts with:

Java HotSpot™ 64-Bit Server VM warning: Options -Xverify:none and -noverify were deprecated in JDK 13 and will likely be removed in a future release.
… followed by 16 the lines of my (hopefully) correct solution.

The exact failing message is because of the unexpected 17th line (the last line I sent, which should have been the 16th, but of course the warning shifted them)

Kotlin works well on at least another problem, which I have solved successfully.

Is there anything I can do to avoid that ? Some language feature I’m using which triggers that warning ?

thanks in advance for the investigation,


I have the same issue. Can we have some attention from the Codingame team please?

Not sure if the CodinGame staff checks the forum frequently. You’ll have better chances of having issues fixed by reporting on CodinGame’s Discord #bug-report channel instead.
