If you haven't looked at IBM in the last year (and you sound like you haven't) you are out of date friend... Not only do they have an entire JDK available, they have profilers and a ton of other FREE tools out there... (XML stuff, pure Java installers, etc etc)
http://www.ibm.com/java/jdk/index.html "IBM provides developer kit code for AIX, OS/2, OS/390 (UNIX Services), OS/400, VM/ESA, Linux and Windows(R). You can download the code (without payment) either from this site, or from some other part of IBM's web linked to from this site. These are the Java developer kits available now. "

The Linux JRE (with JIT) from IBM is as fast as their WinTel version... and it's substantially faster than Sun's ~and~ MS's...
