ehcache monitor启动错误UnknownHostException

@echo on

if not defined JAVA_HOME (
  echo JAVA_HOME environment variable must be set
  exit /b 1
)

setlocal enabledelayedexpansion
set JAVA_HOME="%JAVA_HOME:"=%"
set PRGDIR=%~d0%~p0..
set PRGDIR="%PRGDIR:"=%"
set classpath=
for %%F in (%PRGDIR%\lib\*.jar) do (
  set classpath=!classpath!;%%F%
)

Windows下用原始的startup.bat启动monitor会报一个java.net.UnknownHostException, 比较莫名其妙，根据启动log来看基本上应该这个脚本找的Jetty.xml有问题，直接去掉那个-j选项后，可以启动成功
以下是monitor的启动脚本：

java ^
   %JAVA_OPTS% ^
   -server ^
   -Dehcachedx.sampling.seconds=10 ^
   -Dehcachedx.sampling.history=8640 ^
   -server ^
   -cp %classpath% ^
   org.terracotta.ehcachedx.monitor.Monitor start ^
   -j %PRGDIR%\etc\jetty.xml ^ 去掉
   -f ..\etc\ehcache-monitor.conf %*

endlocal

启动成功后显示以下界面：
