Robocode 1.9.4.8

Version 1.9.4.8 (29-Nov-2022) Reworked Disabling Security Manager

Bugfixes

  • Rendering issues on Windows using accelerated hardware, by setting this Java properties:
    • sun.java2d.d3d=false (turn off use of Direct3D)
    • sun.java2d.ddoffscreen=false (turn of Direct Draw off-screen)
    • sun.java2d.noddraw=true (no use of Direct Draw)
    • sun.java2d.opengl=True
  • Adding -source 1.5 to the ECJ compiler options to prevent "...only available if source level is 1.5 or greater" error when compiling with ECJ.

Improvements

  • Security Manager: When setting the NOSECURITY=true (e.g. via the -DNOSECURITY=true property in the java command-line), then internal security manager of Robocode is now totally disabled, and falling back on the default security manager used in Java.
    • This fixes issues with the class loader not being able to find classes resulting in ClassNotFoundExceptions, and other issues as well.
  • Updated built-in Eclipse Compiler for Java (ECJ) to version 3.26 (June 2021), which is the last version of ECJ capable to run on Java 8 (newer ECJ versions requires Java 11 as minimum).
