Subject [jira] Created: (GERONIMO-644) Serialized form of GBeans objects must each declare SUID
Date Tue, 10 May 2005 10:22:08 GMT
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


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.
