Ivo Studensky created JBTM-1076: ----------------------------------- Summary: Uid serialization violates java serialization spec Key: JBTM-1076 URL: https://issues.jboss.org/browse/JBTM-1076 Project: JBoss Transaction Manager Issue Type: Bug Security Level: Public (Everyone can see) Components: Transaction Core Affects Versions: 4.16.2 Reporter: Ivo Studensky Assignee: Tom Jenkinson Fix For: 4.16.3 According to the Java serialization spec each private writeObject method should call either defaultWriteObject or writeFields method. This is missing in com.arjuna.ats.arjuna.common.Uid#writeObject() method. Similar issue also affects the readObject method of the Uid class. See the spec: http://docs.oracle.com/javase/6/docs/platform/serialization/spec/output.h... I've identified this bug when I tried to use RecoveryStoreProxy from the client side against AS7 via JMX. The invocation of allTypes or remove_committed methods failed due to: {noformat} Caused by: java.io.NotActiveException: Fields were never written at org.jboss.marshalling.river.RiverObjectOutputStream.finish(RiverObjectOutputStream.java:175) at org.jboss.marshalling.river.RiverMarshaller.doWriteSerializableObject(RiverMarshaller.java:1009) at org.jboss.marshalling.river.RiverMarshaller.doWriteObject(RiverMarshaller.java:885) at org.jboss.marshalling.AbstractObjectOutput.writeObject(AbstractObjectOutput.java:62) at org.jboss.marshalling.AbstractMarshaller.writeObject(AbstractMarshaller.java:119) at org.jboss.remotingjmx.protocol.v1.ClientConnection$TheConnection$15.write(ClientConnection.java:1181) at org.jboss.remotingjmx.protocol.v1.Common.write(Common.java:179) at org.jboss.remotingjmx.protocol.v1.ClientConnection$TheConnection.invoke(ClientConnection.java:1163) at javax.management.MBeanServerInvocationHandler.invoke(MBeanServerInvocationHandler.java:288) ... 92 more Caused by: an exception which occurred: in object com.arjuna.ats.arjuna.common.Uid@0 {noformat} -- This message is automatically generated by JIRA.
