Hi, I have install Jboss Developer Studio plugin in my eclipse Kepler. After installation, I removed all the VM arguments except -server paramter. my final VM arguments from server configuration looks as follows -server -Xms128m -Xmx2G -XX:MaxPermSize=512m Image:Modified.png But once I save the configuration and close the window, The VM arguments are getting replaced to default except -server parameter as below -server -Xms128m -Xmx2G -XX:MaxPermSize=512m -Djboss.home.dir=D:/jboss-standalone-config -Dorg.jboss.boot.log.file=D:/jboss-standalone-config/standalone/log/boot.log -Dlogging.configuration=file:/D:/jboss-standalone-config/standalone/configuration/logging.properties Image:Modified1.png Is there an existing bug with Jboss Developer studio server configuration?
