Re: [Hawkular-dev] hawkular java agent now supports ${x} in config
It was pointed out to me (which I forgot) that WildFly itself supports the syntax ${env.X}
to denote environment variables.
Now, this Java Agent isn't based on WildFly and these ${x} tokens appear in the yaml
file and not the standalone.xml so we technically do no have to be consistent with WildFly
syntax, but I wonder if I should switch this anyway to use the ${env.X} syntax just to
make it consistent for people that are familiar with WildFly syntax.
Let me know - this would be a trivial change but I would like to make another release
quickly if this change is to be made.
