### Describe the bug ## Problem A BPMN process declaring a `java.lang.Object` variable fails to build with: ``` Java type `java.lang.Object` is not supported by Kogito persistence, please consider using a class that extends java.io.Serializable ``` The error is thrown by `AbstractProtoGenerator.protoType()` during proto schema generation. The runtime marshaller already handles `Object` variables correctly — only the build step is broken. ## Changes - **`AbstractProtoGenerator`** — map `java.lang.Object` to `kogito.Serializable` with a build-time warning instead of throwing. - **`ModelMetaData` / `WorkItemModelMetaData`** — emit a warning when `Object` is used as a variable type. - **`JsonSchemaGenerator`** — exclude `Object`-typed fields from the generated JSON schema with a warning. ## Notes - Runtime persistence will fail if the actual value does not implement `java.io.Serializable` — this is by design. - Full form support for `Object`-typed user task variables is a follow-up. ### Expected behavior _No response_ ### Actual behavior _No response_ ### How to Reproduce? _No response_ ### Output of `uname -a` or `ver` _No response_ ### Output of `java -version` _No response_ ### GraalVM version (if different from Java) _No response_ ### Kogito version or git rev (or at least Quarkus version if you are using Kogito via Quarkus platform BOM) _No response_ ### Build tool (ie. output of `mvnw --version` or `gradlew --version`) _No response_ ### Additional information _No response_ -- This is an automated message from the Apache Git Service.
