[jboss-jira] [JBoss JIRA] (AS7-6328) SingletonService fails with NullPointerException when bound to 0.0.0.0

SingletonService fails with NullPointerException when bound to 0.0.0.0 ----------------------------------------------------------------------- Key: AS7-6328 URL: https://issues.jboss.org/browse/AS7-6328 Project: Application Server 7 Issue Type: Bug Components: Clustering Affects Versions: 7.1.2.Final (EAP) Environment: OS independent, reproduces on Ubuntu 12.10 and Windows XP. Reporter: Patrik Varga Assignee: Paul Ferraro Priority: Critical Assume that you have working deployment with a custom MSC service wrapped into a SingletonService. When you are trying to access the value of the SingletonService, the SingletonService.getValue() call fails with NullPointerException iff the JBoss instance is listening on all interfaces, i.e. it is bound to 0.0.0.0 by using <inet-address value="0.0.0.0"/> or <any-address/> under <interface name="public"> in standalone-full-ha.xml. It works when specifying an explicit IP. Example: try the cluster-ha-singleton jboss-as-quickstart Top of the stack trace: java.lang.NullPointerException at org.jboss.as.clustering.singleton.SingletonService.getValue(SingletonService.java:176) at org.jboss.as.clustering.singleton.SingletonService.getValue(SingletonService.java:53) at org.jboss.msc.service.ServiceControllerImpl.getValue(ServiceControllerImpl.java:1203) [...]
