[jboss-as7-dev] Configuration conundrum with Express

[Scott Stark]

Thanks. I'll check against the attributes I'll need and raise issues to 
address those I find missing.

One issue I see is that we are only looking to System.getProperty(name) 
for the value of an expression in the org.jboss.dmr.ExpressionValue 
class. The expressions I'm typically using need to be queried using 
System.getenv(name). Would it be ok to fallback to a System.getenv(name) 
if there is no System.getProperty(name) value found? This would require 
an update to the dmr project.
