I am able to reproduce this using Java 11.=20
It seems to work fine under Java 8. So you can use Java 8 as a workaround=
=20
until I got a fix for it in Robocode as it seems to be a bug.

The issue is caused by some internal classes in Java that have changed,=20
which Robocode accesses.=20

On Stack Overflow, people have seen similar issues with Spring Boot as well=
.

Thank you for reporting this. I will try to fix it with the next version of=
=20
Robocode. =F0=9F=99=82=F0=9F=91=8D

Best regards,
