And JVM has had a JIT compiler since 96.

For the record, HotSpot came out in 1999 and became the default in Java 1.3, which was released in 2000. The HotSpot JVM was also not a particularly portable program, so the performance benefits of JIT were by no means universal to all Java platforms. (Which was fine by Sun because it meant that for reasonable server-side performance you pretty much had to be running Solaris.)

For the record, JIT compiler (not a HotSpot compiler) become available in JVM 1.1 in 96. This JVM actually had a pluggable JIT interface, so there was a couple of custom JITs.

The first HotSpot JIT was present in JRE 1.2 (that's why it was called 'Java 2') later in 97.

I suppose that adding a JIT that finally delivered on the research done previously on Self at Sun Microsystems probably did merit a major version bump, but Sun (and coincidentally Oracle) were masters at a bit of version bumping to warm over products getting a lukewarm reception.

For the record, I stumbled upon Java, Tcl/Tk, Python and a bunch of other languages at the same time, in around 1995. Java was the only one that needed me to get a disk quota upgrade and an account on a flaky Solaris server (whereas the others all ran on SunOS and a multitude of other platforms). I recall a colleague during my summer job showing me Java for the first time: Duke the Java mascot waving in an applet; premium UltraSPARC workstation required.

To be fair, I did get some mileage out of Java for a university project, doing a bit of graphics in AWT instead of using Xlib like everybody else, but a few months later I would saved myself the hassle of the dubious AWT implementation and used something like Python and Tk instead.

Sorry, how did we get onto this again?
