According to this post on the Geronimo devlist, Geronimo 1.1.1 was certified on Azul appliances.
“The testing was performed on an Azul Compute Appliance Model 1920B (8 chip / 192 cores, 64GB memory) coupled with Azul VM release 18.104.22.168 (HotSpot™ Java™ 1.4.2_12), 64-bit Server mode. ”
That’s quite the machine to get to play with! ;-)
