Subject [jira] Updated: (GERONIMO-644) Serialized form of GBeans objects must each declare SUID
Date Thu, 17 Nov 2005 12:07:42 GMT
     [ http://issues.apache.org/jira/browse/GERONIMO-644?page=all ]

Matt Hogstrom updated GERONIMO-644:
-----------------------------------

    Fix Version: 1.x
                     (was: 1.0)

We need to address this issue but its not likely to be resolved in the next few weeks.  Deferring
to 1.x and would like Dain's comments on how xbean may help to reduce this issue.

> 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.
