解決：

if [ "${debugFlag}" = "true" ] ; then
        JAVA_DEBUG="-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=${DEBUG_PORT},server=y,suspend=n -Djava.compiler=NONE"
        export JAVA_DEBUG
        JAVA_OPTIONS="${JAVA_OPTIONS} ${enableHotswapFlag} -ea -da:com.bea... -da:javelin... -da:weblogic... -ea:com.bea.wli... -ea:com.bea.broker... -ea:com.bea.sbconsole...-Djava.net.preferIPv4Stack=true"

else        JAVA_OPTIONS="${JAVA_OPTIONS} ${enableHotswapFlag} -da 
-Djava.net.preferIPv4Stack=true"
        export JAVA_OPTIONS
目前的版本是需要IPV4來實現，IPv6不可以，所以要明確指出IPv4，屏蔽IPv6
