Such a solution would require that JBoss Tools parse the file since we have a chicken/egg problem with VM launching on standalone, and we don't want to have a JVM launching a JVM in a standalone setup (adds too much time to boot). It might also require that we write a native launcher on windows.

For me there are two different kind of arguments/parameters.

The one that are JVM specific/required at Java VM startup and those that are non-JVM specific and can be read by the launcher it self.

It is the latter I'm suggesting to externalize.

OS specific/required at Java VM is currently for standalone.sh (as far as I can see?):

-d32 
-client 
-Xms64m 
-Xmx512m 
-XX:MaxPermSize=256m 
-Djava.net.preferIPv4Stack=true  
-Dsun.rmi.dgc.client.gcInterval=3600000* 
-Dsun.rmi.dgc.server.gcInterval=3600000*
-Djava.awt.headless=true*
-jar "/Users/max/jboss-runtimes/jboss-as-7.1.0.Final-SNAPSHOT/jboss-modules.jar"

*=might not be necessary to setup - depend if those are not getting activated during jboss modules.

Arguments that I would think could be derived by the java launch instead of at command line:

-Dorg.jboss.resolver.warning=true 
-Djboss.modules.system.pkgs=org.jboss.byteman 
"-Dorg.jboss.boot.log.file=/Users/max/jboss-runtimes/jboss-as-7.1.0.Final-SNAPSHOT/standalone/log/boot.log" 
"-Dlogging.configuration=file:/Users/max/jboss-runtimes/jboss-as-7.1.0.Final-SNAPSHOT/standalone/configuration/logging.properties" 
-mp "/Users/max/jboss-runtimes/jboss-as-7.1.0.Final-SNAPSHOT/modules" 
-jaxpmodule javax.xml.jaxp-provider org.jboss.as.standalone 
-Djboss.home.dir="/Users/max/jboss-runtimes/jboss-as-7.1.0.Final-SNAPSHOT"

Most of these could just be calculated based on jboss.home.dir as a nice default.

Leaving us with:

-Dorg.jboss.resolver.warning=true 
-Djboss.modules.system.pkgs=org.jboss.byteman 
-jaxpmodule javax.xml.jaxp-provider

Which could be read in via a properties file or even defaulted?

But Jason, I'm reading your mail as you even want to go to the length of having the vm arguments externalized?
