Listing JNDI tree from container when an entry is not available causes exception -------------------------------------------------------------------------------- Key: WFLY-1421 URL: https://issues.jboss.org/browse/WFLY-1421 Project: WildFly Issue Type: Bug Components: Naming Affects Versions: 8.0.0.Alpha1 Reporter: Jan Martiska Assignee: Eduardo Martins When you list server's JNDI tree using management APIs and some entries cannot be retrieved, instead of these entries, it will return a marker denoting an unknown value. However, if you list the JNDI tree programatically from within the container and this happens, you get a NamingException. I believe that the listBindings operation should also return a marker for an unknown value (like null), rather than failing the whole operation. How to reproduce: Bind a federated JNDI context, like so: {noformat} /subsystem=naming/binding=java\:global\/tt:add(binding-type=external-context, module=org.jboss.as.naming, class=javax.naming.directory.InitialDirContext, environment={["java.naming.provider.url"=>"ldap://some.ldap.url:389", "java.naming.factory.initial"=>"com.sun.jndi.ldap.LdapCtxFactory", "initial-context-class"=>"javax.naming.directory.InitialDirContext"]}, cache=false) {noformat} then, at some point in time, make this context become unavailable, for example stop the backing LDAP server (or block the connection to it using a firewall..). *Other option* - as a simpler reproducer, you may just add any invalid URL in the java.naming.provider.url property, then it will fail always. After that, do this in a deployed application: {noformat} InitialContext ctx = new InitialContext(); ctx.listBindings("java:global"); {noformat} it will throw a NamingException after the connection attempt times out. {noformat} javax.naming.NamingException: java.lang.reflect.InvocationTargetException [Root exception is java.lang.RuntimeException: java.lang.reflect.InvocationTargetException] at org.jboss.as.naming.ServiceBasedNamingStore.lookup(ServiceBasedNamingStore.java:142) at org.jboss.as.naming.ServiceBasedNamingStore.listBindings(ServiceBasedNamingStore.java:216) at org.jboss.as.naming.NamingContext.listBindings(NamingContext.java:347) at org.jboss.as.naming.InitialContext.listBindings(InitialContext.java:131) at org.jboss.as.naming.NamingContext.listBindings(NamingContext.java:363) at javax.naming.InitialContext.listBindings(InitialContext.java:466) [rt.jar:1.7.0_21] at ListingServlet.doGet(ListingServlet.java:30) ... 33 more Caused by: java.lang.RuntimeException: java.lang.reflect.InvocationTargetException at org.jboss.as.naming.subsystem.NamingBindingAdd$2.getReference(NamingBindingAdd.java:258) at org.jboss.as.naming.ServiceBasedNamingStore.lookup(ServiceBasedNamingStore.java:140) ... 39 more Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) [rt.jar:1.7.0_21] at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) [rt.jar:1.7.0_21] at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) [rt.jar:1.7.0_21] at java.lang.reflect.Constructor.newInstance(Constructor.java:525) [rt.jar:1.7.0_21] at org.jboss.as.naming.ExternalContextObjectFactory.createContext(ExternalContextObjectFactory.java:87) at org.jboss.as.naming.ExternalContextObjectFactory.getObjectInstance(ExternalContextObjectFactory.java:52) at org.jboss.as.naming.subsystem.NamingBindingAdd$2.getReference(NamingBindingAdd.java:255) ... 40 more Caused by: javax.naming.CommunicationException: ldap.cz:3890 [Root exception is java.net.ConnectException: Connection timed out] at com.sun.jndi.ldap.Connection.<init>(Connection.java:224) [rt.jar:1.7.0_21] at com.sun.jndi.ldap.LdapClient.<init>(LdapClient.java:136) [rt.jar:1.7.0_21] at com.sun.jndi.ldap.LdapClient.getInstance(LdapClient.java:1600) [rt.jar:1.7.0_21] at com.sun.jndi.ldap.LdapCtx.connect(LdapCtx.java:2698) [rt.jar:1.7.0_21] at com.sun.jndi.ldap.LdapCtx.<init>(LdapCtx.java:316) [rt.jar:1.7.0_21] at com.sun.jndi.ldap.LdapCtxFactory.getUsingURL(LdapCtxFactory.java:193) [rt.jar:1.7.0_21] at com.sun.jndi.ldap.LdapCtxFactory.getUsingURLs(LdapCtxFactory.java:211) [rt.jar:1.7.0_21] at com.sun.jndi.ldap.LdapCtxFactory.getLdapCtxInstance(LdapCtxFactory.java:154) [rt.jar:1.7.0_21] at com.sun.jndi.ldap.LdapCtxFactory.getInitialContext(LdapCtxFactory.java:84) [rt.jar:1.7.0_21] at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:684) [rt.jar:1.7.0_21] at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:307) [rt.jar:1.7.0_21] at javax.naming.InitialContext.init(InitialContext.java:242) [rt.jar:1.7.0_21] at javax.naming.InitialContext.<init>(InitialContext.java:216) [rt.jar:1.7.0_21] at javax.naming.directory.InitialDirContext.<init>(InitialDirContext.java:101) [rt.jar:1.7.0_21] ... 47 more Caused by: java.net.ConnectException: Connection timed out at java.net.PlainSocketImpl.socketConnect(Native Method) [rt.jar:1.7.0_21] at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:339) [rt.jar:1.7.0_21] at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:200) [rt.jar:1.7.0_21] at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:182) [rt.jar:1.7.0_21] at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:391) [rt.jar:1.7.0_21] at java.net.Socket.connect(Socket.java:579) [rt.jar:1.7.0_21] at java.net.Socket.connect(Socket.java:528) [rt.jar:1.7.0_21] at java.net.Socket.<init>(Socket.java:425) [rt.jar:1.7.0_21] at java.net.Socket.<init>(Socket.java:208) [rt.jar:1.7.0_21] at com.sun.jndi.ldap.Connection.createSocket(Connection.java:366) [rt.jar:1.7.0_21] at com.sun.jndi.ldap.Connection.<init>(Connection.java:201) [rt.jar:1.7.0_21] ... 60 more {noformat}
