After 20 years of Java we still don't have our perfect VM. It still sees critical security vulnerabilities. I don't think I'm picking on Java unfairly here. Java is a well written code base, it has plenty of unit tests, a proper code review process, a sound architecture. Pretty much all of these have been put forward as ideas that would 'cure' the OpenSSL project. Yet it doesn't seem to be a perfect cure. At some point no matter what your language, VM, OS is you are going to experience something similar.
