Issues with EAP6 alternate server runtime configuration in JBoss Developer Studio 5

Issue

• I copied the eap6 'standalone' directory to my own directory called "custom".
• I did the Redhat JBoss Dev Studio with EAP 6 installation.
• Starting the standalone server that is configured out of the box works fine.
• When I start 'custom' though (via JBoss Dev Studio), I get an error. I have set the configuration file location to:

<jboss_eap_path>\custom\configuration\standalone-full.xml using the GUI.

• In starting the server, I get the following error:

"The server's configuration file does not exist: <jboss_eap_path>\standalone\configuration\<jboss_eap_path>\custom\configuration\standalone-full.xml"

• It's (JBoss Dev Studio) concatenating two locations together.
• I have tried setting additional -D props in the launch configuration window, but they doesn't work as well

Program Arguments:
-mp <jboss_eap_path>/modules -jaxpmodule javax.xml.jaxp-provider org.jboss.as.standalone -b localhost --server-config=<jboss_eap_path>\custom\configuration\standalone-full.xml

VM Arguments:
-server -Xms64m -Xmx512m -XX:MaxPermSize=256m -Djava.net.preferIPv4Stack=true -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Djboss.modules.system.pkgs=org.jboss.byteman -Djava.awt.headless=true -Dorg.jboss.boot.log.file=<jboss_eap_path>/custom/log/boot.log -Dlogging.configuration=file:/<jboss_eap_path>/custom/configuration/logging.properties -Djboss.home.dir=<jboss_eap_path>
-Djboss.server.config.dir=<jboss_eap_path>/custom/configuration
-Djboss.server.base.dir=<jboss_eap_path>/custom

• The custom configuration with non-default configuration file works from command line (outside JBoss Developer Studio)
