…rt to 2.43) Backport of #24042. Ehcache's SerializingCopier performs real Java serialization of L2-cached entity state, so every JSONB value type on a cached entity must implement java.io.Serializable. 2.43 is still on Ehcache 3.10.8 (where this does not yet bite), so this is future-proofing plus the guard test that locks the invariant in before the eventual 3.12 bump. - RenderingObject: extend Serializable (covers Section/ValueTypeRenderingObject) - ApiTokenAttribute: implement Serializable (folds in #24002, never backported; ApiToken is L2-cached) - add CachedEntityJsonbSerializableTest guard walking the live Hibernate metamodel so this cannot regress silently Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
mvn dependency:analyze flags the new test's JsonBinaryType import as a used-undeclared dependency. The ignoredNonTestScopedDependencies entry only suppresses the scope check, not used-undeclared, so declare the dependency explicitly (compile scope), matching master.

Backport of #24042 to 2.43.
Ehcache's
SerializingCopierperforms real Java serialization of L2-cached entity state, so every JSONB value type on a cached entity (and its whole object graph) must implementjava.io.Serializable.Note: 2.43 is still on Ehcache 3.10.8, where this does not yet manifest (the regression appears with the 3.12
SerializingCopier, which is already on master and 2.42). This backport is therefore future-proofing, and the guard test locks the invariant in before 2.43 eventually bumps to 3.12.Changes
RenderingObjectextendsSerializable(transitively coversSection/ValueTypeRenderingObject).ApiTokenAttributeimplementsSerializable. Folds in fix: make ApiTokenAttribute Serializable for Ehcache L2 cache #24002, which was never backported to 2.43;ApiTokenis L2-cached, so it would hit the sameNotSerializableExceptiononce 2.43 is on 3.12. Required for the guard test to pass.CachedEntityJsonbSerializableTest, which walks the live Hibernate metamodel and asserts every JSONB value type on an L2-cached entity isSerializable, so this cannot regress silently.Verification
Guard test run locally against Postgres on this branch: 2 tests, 0 failures.
