Actually, -b and -Djboss.bind.address are not exatcly the same. While they both set jboss.bund.address, the -b option also sets java.rmi.server.hostname (under certain conditions, which is why I had you set it sepcifically), and also sets some jgroup-related system properties. Try this. Go into jmx-console, look up the jboss:name=SystemProperties,type=Service MBean, and invoke the showAll operation. Compare the system properties that are host names or IP addresses. If there is a property that has 127.0.0.1 on Qa but some other value on Test, try setting that property using -D.
