[wildfly-dev] [jboss-as7-dev] Domain mode server launch command

[Brian Stansberry]

Hi John,

I copied the wildfly-dev list.

I prefer the <jvm> approach. We already have logic for combining jvm 
configs set at different levels (server-group, host, server) so people 
can set this at whatever level they prefer, and then if they want 
something different for a particular server they can override.

Cheers,

- Brian
