Actually, it has, but the big improvements were between 1.3 and 1.5.
The javac in Java SE 6 doesn't appear to be much different from that in
1.5 in terms of efficiency of the generated byte codes.

Definitely meaner, in that the JITs do produce better code. I certainly
wouldn't describe either of the HotSpot JITs as "lean". (The server
compiler was the basis for a several hundred-page PhD thesis a few years
ago :-)
