my reason for posting is to see if someone can explain this for me.
Environment is weblogic server, but it is using plain sun JVM
Probably some kind of performance optimization the VM is doing...
The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
