[esb-issues] [JBoss JIRA] Updated: (JBESB-2446) The update to the message context has broken serialisation with older versions

The update to the message context has broken serialisation with older versions ------------------------------------------------------------------------------ Key: JBESB-2446 URL: https://jira.jboss.org/jira/browse/JBESB-2446 Project: JBoss ESB Issue Type: Bug Security Level: Public(Everyone can see) Components: Rosetta Affects Versions: 4.4 CP2 Reporter: Kevin Conner Fix For: 4.4 CP3 The message context was previously unused but was modified, by me I must admit, so that we could usefully distinguish between message context and message contents. Unfortunately this breaks when an old version of a serialized message is read by the new version. The fix is straight forward, add the following into the ContextImpl for the serialized format. /** * Deserialise the object, checking for old versions. * @param ois The object input stream. * @throws IOException For IO exceptions during object deserialisation. * @throws ClassNotFoundException If dependent classes cannot be found. */ private void readObject(final ObjectInputStream ois) throws IOException, ClassNotFoundException { ois.defaultReadObject() ; if (context == null) { context = new HashMap<String, Serializable>() ; } } The XML variant is correct.
