Knut Anders Hatlen commented on DERBY-6124:
-------------------------------------------
What's not quite clear to me, is where the serialized object with the old
serialVersionUID comes from. The compatibility test that runs in derbyall does
not use old jar files, as far as I know. Furthermore, the Price class lives in
derbyTesting.jar, and none of the compatibility tests (neither in derbyall nor
in suites.All) use derbyTesting.jar from old versions.
