Just thought people around here would like to know. I just had a customer inform me that my latest game (using LWJGL) works fine with openJDK (on Ubuntu 64-bit edition).
Honestly, I was a bit surprised, but glad that it worked.
That's no surprise to me, I've been running lwjgl game with both the previous icedtea and now openjdk with success on my ubuntu 64 bit. The only missing piece is a decent browser plugin (the current one doesn't support signed applets or liveconnect properly).
