Seam developer and fellow Red Hatter Pete Muir has posted about his adventures with getting Seam running on Fedora 8:

Best thing about his adventure? Pete ran a “highly unscientific test” and found out that IcedTea outperformed other JDKs:
This piqued my interest, so I did a highly unscientific test and installed the Sun JDK 1.5.0_14 and the Sun JDK 1.6.0_03, and (using Seam and the example compiled by JDK 1.5) took a look at how long the server takes to start.
I found that using JDK 5 to boot the server it took 32s, using JDK 6 it took 25s and using Iced Tea (JDK 7) 21s — definitely going in the right directions! I then compiled Seam and the example using Iced Tea, and (running JBoss AS using Iced Tea) got a startup time around 19-20s.
Of course, this no match for a real performance test, but I found it interesting.
