Which java vm is best to use?

[Pulse]

Should I be using JDK 1.5 or 1.4.2? Im assuming that 1.5 is the better to use but it seems. . . experimental ;). Can stuff built on 1.5 be run on 1.4.2 or is that a no-no?

Java seems to come in so many flavours its mind boggling :/.

Does Quake III run on your Commodore 64?

assuming none of the IL defs have changed and youd dont use any new 1.5 functionality you should be able to run stuff compiled on one system with an older one..

So basically its just best to use the latest.

Sparky, I dont own a Commodore 64.

Yeah, there are very few times when its not better to have the most upto date system you can
