Excelsior JET 6.4 Released, Introduces Encryption Of Program Data And Resources

I am glad to write that we have released Excelsior JET 6.4 today. This new version enhances protection of your optimized applications against reverse engineering and tampering by scrambling program data and resources. This includes string literals, reflection information, and any media and property files packed into the executable. On-demand decryption ensures that reflection and JNI remain fully functional, as opposed to name obfuscation, commonly used for protection of Java applications.

More new features and improvements:

  • Startup Optimizer improves the cold startup time of your applications;
  • Not-So-Dumb Compilation: now a settings change that has no impact on generated code results in a re-link instead of a full build;
  • At last, the Installation Toolkit supports inclusion of newer JET Runtime versions into update packages;
  • Faster AOT and JIT compilation;
  • Application performance improvements.
