When did Java first get a JIT compiler for production code?

A:
I believe HotSpot debuted in 1.3, though it was available as a plugin to 1.2.

The original C2/server HotSpot was available for 1.2.2 sometime after it shipped.

October 25, 1996 Sun announces first Just-In-Time (JIT) compiler for Java platform
Also, from wikipedia: Since JRE version 1.2, Sun's JVM implementation has included a just-in-time compiler instead of an interpreter. http://en.wikipedia.org/wiki/Java_(Sun)

This is incorrect, in that Borland and Symantec had them earlier. Also Sun licensed the Symantec one.

1.1.5 had the Semantec JIT, but was not a good release. jview and others were already there. In particular Netscape had had the Semantec JIT for a while.

Production: You would be confident enough to tell your boss that it should be used for a program the company depends on.

That wouldn't be anywhere near the time period of the early jit compilers, imo.

Borland had the first one followed shortly by Symantec. Sun licensed the Symantec one. Symantec demoed theirs in March of 1996.
