…rt to 2.42) Backport of #24042. 2.42 runs Ehcache 3.12 (SerializingCopier), which performs real Java serialization of L2-cached entity state, so every JSONB value type on a cached entity must implement java.io.Serializable. - RenderingObject: extend Serializable (covers Section/ValueTypeRenderingObject) - ApiTokenAttribute: implement Serializable (folds in #24002, never backported; ApiToken is L2-cached, so it hits the same NotSerializableException) - 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 2.42.
2.42 runs Ehcache 3.12 (
SerializingCopier), which performs real Java serialization of L2-cached entity state. Every JSONB value type on a cached entity (and its whole object graph) must therefore implementjava.io.Serializable, or it throwsNotSerializableExceptionat runtime.Changes
RenderingObjectextendsSerializable(transitively coversSection/ValueTypeRenderingObject).ApiTokenAttributeimplementsSerializable. This folds in fix: make ApiTokenAttribute Serializable for Ehcache L2 cache #24002, which was never backported to 2.42 even thoughApiTokenis L2-cached there — so 2.42 currently has the same latent regression. 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.
