Elytron GS2-KRB5 SASL mechanism implementation throws NullPointerException on IBM JDK ------------------------------------------------------------------------------------- Key: ELY-1331 URL: https://issues.jboss.org/browse/ELY-1331 Project: WildFly Elytron Issue Type: Bug Reporter: Josef Cacek Priority: Blocker The Elytron GS2-KRB5 SASL mechanism doesn't work on IBM JDK. When GSSAPI is used the call works. If a user tries to use the GS2-KRB5, then the connection hangs until it times out. Following NPE comes on the client: {noformat} java.lang.NullPointerException at com.ibm.security.krb5.internal.HostAddress.<init>(HostAddress.java:62) at com.ibm.security.jgss.mech.krb5.Z.<init>(Z.java:71) at com.ibm.security.jgss.mech.krb5.g.setChannelBinding(g.java:1108) at com.ibm.security.jgss.GSSContextImpl.setChannelBinding(GSSContextImpl.java:287) at org.wildfly.security.sasl.gs2.Gs2SaslClient.<init>(Gs2SaslClient.java:120) at org.wildfly.security.sasl.gs2.Gs2SaslClientFactory.createSaslClient(Gs2SaslClientFactory.java:116) at org.wildfly.security.sasl.util.SecurityProviderSaslClientFactory.createSaslClient(SecurityProviderSaslClientFactory.java:110) at org.wildfly.security.sasl.util.AbstractDelegatingSaslClientFactory.createSaslClient(AbstractDelegatingSaslClientFactory.java:66) at org.wildfly.security.sasl.util.ProtocolSaslClientFactory.createSaslClient(ProtocolSaslClientFactory.java:50) at org.wildfly.security.sasl.util.AbstractDelegatingSaslClientFactory.createSaslClient(AbstractDelegatingSaslClientFactory.java:66) at org.wildfly.security.sasl.util.ServerNameSaslClientFactory.createSaslClient(ServerNameSaslClientFactory.java:50) at org.wildfly.security.sasl.util.AbstractDelegatingSaslClientFactory.createSaslClient(AbstractDelegatingSaslClientFactory.java:66) at org.wildfly.security.sasl.util.PropertiesSaslClientFactory.createSaslClient(PropertiesSaslClientFactory.java:54) at org.wildfly.security.sasl.util.AbstractDelegatingSaslClientFactory.createSaslClient(AbstractDelegatingSaslClientFactory.java:66) at org.wildfly.security.sasl.util.ServerNameSaslClientFactory.createSaslClient(ServerNameSaslClientFactory.java:50) at org.wildfly.security.sasl.util.FilterMechanismSaslClientFactory.createSaslClient(FilterMechanismSaslClientFactory.java:102) at org.wildfly.security.sasl.util.AbstractDelegatingSaslClientFactory.createSaslClient(AbstractDelegatingSaslClientFactory.java:66) at org.wildfly.security.sasl.util.LocalPrincipalSaslClientFactory.createSaslClient(LocalPrincipalSaslClientFactory.java:74) at org.wildfly.security.sasl.util.PrivilegedSaslClientFactory.lambda$createSaslClient$0(PrivilegedSaslClientFactory.java:64) at org.wildfly.security.sasl.util.PrivilegedSaslClientFactory$$Lambda$77.00000000FC19A650.run(Unknown Source) at java.security.AccessController.doPrivileged(AccessController.java:686) at org.wildfly.security.sasl.util.PrivilegedSaslClientFactory.createSaslClient(PrivilegedSaslClientFactory.java:64) at org.wildfly.security.auth.client.AuthenticationConfiguration.createSaslClient(AuthenticationConfiguration.java:1237) at org.wildfly.security.auth.client.AuthenticationContextConfigurationClient.createSaslClient(AuthenticationContextConfigurationClient.java:347) at org.jboss.remoting3.remote.ClientConnectionOpenListener$Capabilities.handleEvent(ClientConnectionOpenListener.java:418) at org.jboss.remoting3.remote.ClientConnectionOpenListener$Capabilities.handleEvent(ClientConnectionOpenListener.java:242) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) at org.xnio.conduits.ReadReadyHandler$ChannelListenerHandler.readReady(ReadReadyHandler.java:66) at org.xnio.nio.NioSocketConduit.handleReady(NioSocketConduit.java:89) at org.xnio.nio.WorkerThread.run(WorkerThread.java:571) {noformat}
