    Are you sure that it's using it's own java?  Just because it 
installed it doesn't necessarily mean it's using it (one would think so 
but...).  It would be interesting to see what Zend is actually using 
(you may be able to do this in the startup script with a "set -x" or you 
may need to look at it with strace).
