Hi guys, for those of you getting "Exception: java.lang.OutOfMemoryError" or similar errors during GWT compilation of WebAdmin/UserPortal, it's now possible to override default JVM arguments for GWT compiler via command line. For example: $ mvn clean install -Pdep,gwt-admin,gwt-user -Dgwt-plugin.extraJvmArgs="-Xms1024M -Xmx2048M -XX:PermSize=256M -XX:MaxPermSize=512M" Note: you can find default "gwt-plugin.extraJvmArgs" value in $OVIRT_HOME/frontend/webadmin/modules/pom.xml Regards, Vojtech
