> 解决：

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} ${enableHotswapFlag} -ea -da:com.bea... -da:javelin... -da:weblogic... -ea:com.bea.wli... -ea:com.bea.broker... -ea:com.bea.sbconsole...-Djava.net.preferIPv4Stack=true"        export JAVA_OPTIONSelse        JAVA_OPTIONS="${JAVA_OPTIONS} ${enableHotswapFlag} -da -Djava.net.preferIPv4Stack=true"        export JAVA_OPTIONS目前的版本是需要IPV4来实现，IPv6不可以，所以要明确指出IPv4，屏蔽IPv6
