Version 1.9.5.5 (29-Mar-2025)
Changes
- Robocode cannot run with Java 24, which
implemented JEP 486: Permanently Disable the Security Manager.
- Robocode has its own security manager built on top of Java's Security Manager, which has now been removed with
Java 24.
- Robocode will not start up when running Robocode on Java 24 and newer. Instead, an error message is written out
that Robocode does not support Java 24.
- Fixing this issue requires a big rewrite of large parts of the security mechanisms in Robocode to prevent robots
from doing harm on the system and from cheating against other competitor robots in battles.
- Use Java 23 or an older version of Java instead, or head over to the new platform for Robocode:
Robocode Tank Royale.
