Well, the ones I remember: 1. Rebuild everything from source with the tools in Core or Extras at RPM build time, don't just dump binary .class files in the RPM (no matter how they have been built, but definitely not if they have been built with some proprietary Java toolchain). 2. Use aot-compile-rpm to make precompiled .so files for faster operation with GCJ/GIJ and be aware that the resulting packages are NOT noarch packages, but plain old arch-specific packages (just like C/C++ programs). The people working on GCJ on Fedora can certainly tell you more.
