Managed classes that are being changed must:

Previous versions of the class being changed may, or may not, have met any of these requirements. This is legal and allows classes to be changed, without previously meeting these requirements.

The details on how the serialVersionUID is used for class versioning is found in the ActiveSpaces® Transactions Architect's Guide.

The com.kabira.platform.ObjectMismatchTrigger interface is required only if there are non-transparent changes.
