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?)
