Where to get the Free Java SDK?

I use the standart java that I dled from here - http://www.oracle.com/technetwork/java/javase/downloads/index.html

I read in several posts that there is a "free java sdk" that is leighter and the minecraft server runs smothlier on it.

If I misunerstood the name of it, or what it exacly is please corret me and tell me what to download and with what to replace my java that I have installed on my windows machine.

 

I always suggest running Oracle Java. You can run OpenJDK if you want, but it really won't help anything.

 

How come? You say that it isn't leighter or anything? I read several posts saing that they are verry hapy after switching to the OpenJDK, I guess they spoke about this.

 

I mean, I haven't seen any benchmarks that say one is better than the other. Someone "feeling it works better" is great, but is opinion only. You'll also find posts saying the exact opposite.

By all means, give it a try though.

 

OpenJDK is not supported by Minecraft or Bukkit - the information I've gotten is that OpenJDK is apt to break, and doesn't gain any advantages. If you're looking for performance use Java7, that's about all I can recommend other than upgrading your server box.

Basically - Minecraft is written with Sun-Java, and the majority (if not all) plugin developers develop on Sun-Java. There shouldn't be a reason to even consider using openJDK now that Java7 is out.

 

Thx for the good reply!
Will use Java7 then.
