java 11 报错如下：

java.lang.reflect.InaccessibleObjectException: Unable to make public void jdk.internal.ref.Cleaner.clean() accessible: module java.base does not "exports jdk.internal.ref" to unnamed module @efde75f

    at com.dianping.cat.message.internal.MessageIdFactory$1.run(MessageIdFactory.java:266)

这个是java缺少模块导致，解决办法如下,java 启动加入参数

--add-exports=java.base/jdk.internal.ref=ALL-UNNAMED
