[jboss-remoting-issues] [JBoss JIRA] Commented: (JBREM-1072) Synchronize access to static maps in MarshalFactory

Synchronize access to static maps in MarshalFactory --------------------------------------------------- Key: JBREM-1072 URL: https://jira.jboss.org/jira/browse/JBREM-1072 Project: JBoss Remoting Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 2.2.2.SP10, 2.5.0.SP2 (Flounder) Reporter: Ron Sigal Assignee: Ron Sigal Fix For: 2.2.2.SP11, 2.5.0.SP3 (Flounder) Attachments: jboss-remoting.jar Users have experienced the exception org.jboss.remoting.marshal.InvalidMarshallingResource: Can not find a valid marshaller for data type: serializable at org.jboss.remoting.MicroRemoteClientInvoker.invoke(MicroRemoteClientInvoker.java:79) at org.jboss.remoting.Client.invoke(Client.java:1634) at org.jboss.remoting.Client.invoke(Client.java:548) at org.jboss.aspects.remoting.InvokeRemoteInterceptor.invoke(InvokeRemoteInterceptor.java:62) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.tx.ClientTxPropagationInterceptor.invoke(ClientTxPropagationInterceptor.java:67) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.security.SecurityClientInterceptor.invoke(SecurityClientInterceptor.java:53) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.remoting.IsLocalInterceptor.invoke(IsLocalInterceptor.java:74) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.stateless.StatelessRemoteProxy.invoke(StatelessRemoteProxy.java:107) This is strange, since a marshaller for the datatype "serializable" is hardcoded in org.jboss.remoting.marshal.MarshalFactory. However, access to the static Map marshallers is not synchronized, so it's possible that one subsystem is adding a marshaller (e.g., EJB2, JBossMessaging) at the same time that EJB3 is trying to extract a marshaller. The same observation applies to unmarshallers.
