NullPointerException when calling printDetails on cache containing nested clustered SFSB ---------------------------------------------------------------------------------------- Key: EJBTHREE-1661 URL: https://jira.jboss.org/jira/browse/EJBTHREE-1661 Project: EJB 3.0 Issue Type: Bug Components: cache, Clustering Affects Versions: AS 4.2.3.GA Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: Branch_4_2 After invoking an operation spanning a clustered EJB3 SFSB that has a reference to a another clustered EJB3 SFSB, if you try to call printDetails() on the EJB3 SFSB cache, you'll get an exception like this: java.lang.NullPointerException org.jboss.ejb3.stateful.StatefulBeanContext.hashCode(StatefulBeanContext.java:927) java.lang.Object.toString(Object.java:236) java.lang.String.valueOf(String.java:2838) java.lang.StringBuffer.append(StringBuffer.java:236) org.jboss.cache.AbstractNode.printDetailsInMap(AbstractNode.java:176) org.jboss.cache.Node.printDetails(Node.java:411) org.jboss.cache.AbstractNode.printDetailsInMap(AbstractNode.java:185) org.jboss.cache.Node.printDetails(Node.java:411) org.jboss.cache.AbstractNode.printDetailsInMap(AbstractNode.java:185) org.jboss.cache.Node.printDetails(Node.java:411) org.jboss.cache.TreeCache.printDetails(TreeCache.java:4181) sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) java.lang.reflect.Method.invoke(Method.java:616) org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) org.jboss.mx.server.Invocation.invoke(Invocation.java:86) org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) org.jboss.jmx.adaptor.control.Server.invokeOpByName(Server.java:258) org.jboss.jmx.adaptor.control.Server.invokeOp(Server.java:223) org.jboss.jmx.adaptor.html.HtmlAdaptorServlet.invokeOp(HtmlAdaptorServlet.java:276) org.jboss.jmx.adaptor.html.HtmlAdaptorServlet.processRequest(HtmlAdaptorServlet.java:100) org.jboss.jmx.adaptor.html.HtmlAdaptorServlet.doPost(HtmlAdaptorServlet.java:82) javax.servlet.http.HttpServlet.service(HttpServlet.java:637) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) This is due to trying to call to hashCode() on a ProxiedStatefulBeanContext which doesn't contain any containerClusterUid as such. Instead, ProxiedStatefulBeanContext should somehow pass the request for containerClusterUid to its delegate.
