I had a buddy that wrote a Java 1.1 JVM from scratch in C back in late '97. He created it completely from the defined specification from Sun and actually found bugs in the spec. IIRC, the found bugs in the thread(s) specification. I believe his JVM was one of the first clean-room JVM implementation outside of Sun's efforts.

I can imagine that the spec would to some extent reflect an attempt to capture the behavior of the jvm they actually wrote, as opposed to being created first and then having Sun implement afterwards? It sounds like an interesting exercise to recreate it based on the spec and see what got missed.

Their intent was to have hardware implementations. The basic spec is simple enough to make that tractable.
