    Description

      I'm seeing incomptibilities between versions that are simply due to the fact that Serializable/Externalizable classes are letting their serialVersionUIDs float instead of explicitly defining them. We need to get this cleaned up. There should not be a single Serializable/Externalizable class that does not fix its serialVersionUID and then take responsibility for maintaining compatibility with the indicated version.

      The attached SerializableHasSerialVersionUIDField.zip unzips to create a SerializableHasSerialVersionUIDField-index.html and SerializableHasSerialVersionUIDField directory which is a report of all classes in the 4.0 codebase that are not defining a serialVersionUID as they should.

      The JDK object serialization spec defines all you need to know about the apis and contracts for object serialization:
      http://java.sun.com/j2se/1.4.2/docs/guide/serialization/spec/serialTOC.html

      In particular, Versioning of Serializable Objects:
      http://java.sun.com/j2se/1.4.2/docs/guide/serialization/spec/version.html#wp9419

      talks about binary compatibility and what is available to manage this.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
