具体异常如下： javax.management.InstanceNotFoundException: java.lang:type=MemoryPool,name=CMS Perm Gen at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.getMBean(DefaultMBeanServerInterceptor.java:1095) at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.getAttribute(DefaultMBeanServerInterceptor.java:643) at com.sun.jmx.mbeanserver.JmxMBeanServer.getAttribute(JmxMBeanServer.java:678) at javax.management.remote.rmi.RMIConnectionImpl.doOperation(RMIConnectionImpl.java:1445) at javax.management.remote.rmi.RMIConnectionImpl.access$300(RMIConnectionImpl.java:76) at javax.management.remote.rmi.RMIConnectionImpl$PrivilegedOperation.run(RMIConnectionImpl.java:1309) at javax.management.remote.rmi.RMIConnectionImpl.doPrivilegedOperation(RMIConnectionImpl.java:1401) at javax.management.remote.rmi.RMIConnectionImpl.getAttribute(RMIConnectionImpl.java:639) at sun.reflect.GeneratedMethodAccessor31.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:324) at sun.rmi.transport.Transport$1.run(Transport.java:200) at sun.rmi.transport.Transport$1.run(Transport.java:197) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Transport.java:196) at sun.rmi.transport.tcp.TCPTransport.handleMessages(TCPTransport.java:568) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(TCPTransport.java:826) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.lambda$run$0(TCPTransport.java:683) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(TCPTransport.java:682) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteCall.java:276) at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:253) at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:162) at com.sun.jmx.remote.internal.PRef.invoke(Unknown Source) at javax.management.remote.rmi.RMIConnectionImpl_Stub.getAttribute(Unknown Source) at javax.management.remote.rmi.RMIConnector$RemoteMBeanServerConnection.getAttribute(RMIConnector.java:903) at jrds.probe.JMX.getNewSampleValuesConnected(JMX.java:67) at jrds.probe.JMX.getNewSampleValuesConnected(JMX.java:33) at jrds.ProbeConnected.getNewSampleValues(ProbeConnected.java:64) at jrds.Probe.collect(Probe.java:501) at jrds.starter.HostStarter.collectAll(HostStarter.java:44) at jrds.starter.Timer$3.run(Timer.java:129) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)

这块的jrds-mycat包源码有不？老版本不支持jdk8

jdk7也存在这个问题

并且配置【Mycat-配置/Mycat-VM管理】中不添加监控，日志中仍然会进行jmx读取，一直产生log错误堆栈日志

这块源码缺失严重 改动成本太大 先将就用着了

1.8没有了永久代，而mycat是基于1.7版本的。所以一直报错，我是这么理解的。
