## What is the purpose of the change Fix [FLINK-41001](https://issues.apache.org/jira/browse/FLINK-41001): the OpenAI provider rejects model input schemas declared as `CHAR(n)`, bounded `VARCHAR(n)`, or `STRING NOT NULL` because it requires an exact nullable, unbounded `STRING` type. Accept compatible character string types in the shared Java provider validation so both chat and embedding models benefit through SQL and Table API. ## Brief change log - Accept `CHAR` and `VARCHAR` input types regardless of length or nullability. - Preserve output schema, column count, and metadata validation. - Extend existing model tests with prediction planning coverage for compatible input types and invalid output types. ## Verifying this change This change added tests and can be verified as follows: - Chat model tests cover nullable and non-nullable `CHAR`, bounded `VARCHAR`, and unbounded `STRING` inputs through SQL and anonymous-model Table API calls. An embedding model test covers bounded, non-nullable string input. - Parameterized output validation tests retain the exact output type requirement. All added cases only plan queries; they add no MiniCluster jobs. - The new input cases reproduce the original validation failures without the fix. The complete OpenAI model suite passed on the new base: **32 tests**. - The standalone SQL reproducer from the Jira description plans successfully with the rebuilt provider. - Spotless, Checkstyle, and the root reactor package build with tests skipped passed. Full `clean verify` has not been run. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): no - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: no - The serializers: no - The runtime per-record code paths (performance sensitive): no - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: no - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? no - If yes, how is the feature documented? not applicable --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes (please specify the tool below) Generated-by: Codex (GPT-6) -- This is an automated message from the Apache Git Service.
