I misread the merge date in the wiki. Hotspot merged into mainline in Java 1.3 in 2000. It was first released as a separate distributable.

That said, in the paper they didn't use sun's JVM they used gcj and their own modified version of gcj.

> We examined the performance of both our new Java implementation as well as standard gcj on a variety of Java applications.

So my point still stands, a lot as changed. The researches chose to use static compilation over a JIT or interpreter.
