Robocode 1.10.3

Version 1.10.3 (18-May-2026)

Bugfix

• #85: Fix NPE causing truncated battles when a robot thread stop is attempted
  • If the thread stop fails, a NullPointerException was thrown which aborted the battle early, resulting in battles
    being reported with results but the wrong number of rounds.
    The fix takes a reference to the thread beforehand so the NPE is avoided when forceStop() sets it to null.
  • Thanks go to Julian Kent for fixing this ❤️. Nice catch!
