JOPA: Java compiler in C++, Jikes modernized to Java 6 with Claude

Essentially, I've tried to throw a task which, I thought, Claude won't handle. It did with minimal supervision. Some things had to be done in "adversarial" mode where Claude coded and Codex criticized/reviewed, but it is what it is. An LLM was able to implement generics and many other language features with very little supervision in less than a day o_O.

I've been thrilled to see it using GDB with inhuman speed and efficiency.
