Subject [jira] Commented: (GERONIMO-644) Serialized form of GBeans objects must each declare SUID

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;
----

> 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.
