Thread:Talk:Code Size/Writing nanobots using Java Assembly directly

It seems that openjdk has a wonderful tool called asmtools that allows two directional transformation between jasm and .class bytecode

https://wiki.openjdk.java.net/display/CodeTools/asmtools

Has anyone tried writing robocode bots with java assembly directly? Since the relationship between Java and Bytecode is not as direct as jasm and bytecode, writing with jasm directly may be a better way than tricks listed on this wiki.
