Rusty JVM

A JVM interpreter written in Rust from scratch — no dependency on existing JVMs.

rusty-jvm executes Java bytecode in interpreted mode and aims to support as much of the Java language as possible. Currently supports a range of Java language features up to Java 23 (excluding GC and lambdas for now).
