[ http://issues.apache.org/jira/browse/GERONIMO-644?page=comments#action_65490 ] Tim Ellison commented on GERONIMO-644: --------------------------------------
There is a handy Eclipse compile time check for "Serializable class without serialversionUID", which would catch them all at compile time, but for now here's a couple I found with a runtime test bringing up bin\server.jar on 1.0-M3. ---- The class org.codehaus.activemq.message.DefaultWireFormat does not declare an SUID. To retain compatibility with existing persistent form it should declare: static final long serialVersionUID =-8707485428936851184L; ---- There is a serializable class hierarchy rooted at org.apache.geronimo.gbean.GAttributeInfo that does not declare a SUID. Bringing up the bin\server.jar exposed: org.apache.geronimo.gbean.DynamicGAttributeInfo which to retain compatibility with existing persistent forms should declare static final long serialVersionUID =-3766690289494192629L; ---- > Serialized form of GBeans objects must each declare SUID > -------------------------------------------------------- > > Key: GERONIMO-644 > URL: http://issues.apache.org/jira/browse/GERONIMO-644 > Project: Geronimo > Type: Bug > Reporter: Tim Ellison > Assignee: Jeremy Boynes > > Since Geronimo exchanges config information via serialized form of Java > objects, its imperative that the serializable classes declare a > serialVersionUID. If they don't then the serialized form is not necessarily > compatible across Java implementations (or even Java compilers) [1]. > The case in point is the wire format classes in ActiveMQ (e.g. > "org.codehaus.activemq.message.DefaultWireFormat") which are marked > serializable and do not declare a static ID. I've tried raising this with > ActiveMQ [2] but without success. > I can provide the required SUID in each case, but it looks like I might need > help to get it into the ActiveMQ code. > [1] > http://java.sun.com/j2se/1.3/docs/guide/serialization/spec/class.doc6.html#4100 > [2] http://article.gmane.org/gmane.comp.java.activemq.devel/486 -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
