>
> Inside Configuration.substituteVars(), there is a call to
> System.getProperty(var); this contains the implicit assumption that the JVM
> will never block access to a system property, because if that is the case
> -such as when the Configuration is running under a restrictive security
> manager, a SecurityException gets thrown. This will get thrown all the way up
> the tree.
> Better to have some plan to handle it in situ, such as a [EMAIL PROTECTED]
> level then leave the property unexpanded.
