Problematic casting to String in org.jboss.jmx.connector.invoker.AuthenticationInterceptor ------------------------------------------------------------------------------------------ Key: JBAS-4344 URL: https://jira.jboss.org/jira/browse/JBAS-4344 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: JMX Affects Versions: JBossAS-4.0.4.GA Environment: Mac Os X, RedHat Reporter: David Dossot Assignee: Anil Saldhana There is a problematic cast in org.jboss.jmx.connector.invoker.AuthenticationInterceptor.invoke(Invocation invocation) on line 110: String opname = (String) obj[1]; When Twiddling to get a particular attribute, the following code is used in org.jboss.console.twiddle.command.GetCommand.execute(String[] args) on line 165: attributeNames.toArray(names); (...) AttributeList attrList = server.getAttributes(objectName, names); So obj[1] ends up holding a String[] of attribute names (even if there is only one) and the cast fails: 14:14:44,760 ERROR [Twiddle] Exec failed java.lang.ClassCastException: [Ljava.lang.String; cannot be cast to java.lang.String at org.jboss.jmx.connector.invoker.AuthorizationInterceptor.invoke(AuthorizationInterceptor.java:107) at org.jboss.jmx.connector.invoker.AuthenticationInterceptor.invoke(AuthenticationInterceptor.java:108) at org.jboss.mx.server.Invocation.invoke(Invocation.java:88) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) at org.jboss.invocation.jrmp.server.JRMPProxyFactory.invoke(JRMPProxyFactory.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:589) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) at org.jboss.mx.server.Invocation.invoke(Invocation.java:86) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) at org.jboss.invocation.jrmp.server.JRMPInvoker$MBeanServerAction.invoke(JRMPInvoker.java:819) at org.jboss.invocation.jrmp.server.JRMPInvoker.invoke(JRMPInvoker.java:420) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:589) at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:305) at sun.rmi.transport.Transport$1.run(Transport.java:159) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Transport.java:155) at sun.rmi.transport.tcp.TCPTransport.handleMessages(TCPTransport.java:535) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(TCPTransport.java:790) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(TCPTransport.java:649) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:679) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:704) at java.lang.Thread.run(Thread.java:637) at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteCall.java:255) at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:233) at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:142) at org.jboss.invocation.jrmp.server.JRMPInvoker_Stub.invoke(Unknown Source) at org.jboss.invocation.jrmp.interfaces.JRMPInvokerProxy.invoke(JRMPInvokerProxy.java:133) at org.jboss.invocation.InvokerInterceptor.invokeInvoker(InvokerInterceptor.java:331) at org.jboss.invocation.InvokerInterceptor.invoke(InvokerInterceptor.java:194) at org.jboss.jmx.connector.invoker.client.InvokerAdaptorClientInterceptor.invoke(InvokerAdaptorClientInterceptor.java:66) at org.jboss.proxy.SecurityInterceptor.invoke(SecurityInterceptor.java:70) at org.jboss.proxy.ClientMethodInterceptor.invoke(ClientMethodInterceptor.java:74) at org.jboss.proxy.ClientContainer.invoke(ClientContainer.java:100) at $Proxy0.getAttributes(Unknown Source) at org.jboss.console.twiddle.command.GetCommand.execute(GetCommand.java:168) at org.jboss.console.twiddle.Twiddle.main(Twiddle.java:305)
