If you turn Tag CFObject /
function CreateObject off in the Railo Server Administrator -> Security -> access you get an error when you use the <cfdump> tag. This error currently reads:
can't create Java Object [railo.commons.color.ColorCaster],
direct java access is deinied by security manager
a suggested rewording would be:
Can't create Java object [railo.commons.color.ColorCaster]: direct Java access is denied by the Security Manager.
