Or the list would have to become: Spring, Spring in WLS, Spring in WAS, Spring in ..., WLS alone, WAS, ... .Plus versions.
I would say there will really be just one spring 'platform'. But that has to be confirmed by running some war on WLS/WAS with the debugger's help. Someone could also let the spring guys know that in certain setup their configuration for EL is wrong (perhaps file a bug in their tracker and/or provide warning on our end if we're able to detect such case?)
