SEPURI-SAI-KRISHNA opened a new issue, #12617: URL: https://github.com/apache/seatunnel/issues/12617
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened Eleven sites in `seatunnel-transforms-v2` convert case without a `Locale`, so they follow the worker's default locale. Under `tr-TR` the letter `i` does not round trip: `"if".toUpperCase()` is `"İF"` and `"GIF".toLowerCase()` is `"gıf"`. Same class as #12496, fixed for the `sql` subtree by #12495; these are the rest, in `calcite`, `nlpmodel` and `validator`. **Five are reachable today, each reproduced by a unit test that fails on `dev`:** | Site | Effect under `tr-TR` | | --- | --- | | `calcite/udf/VectorReduceFunction.java:60` | `VECTOR_REDUCE(vec, 2, 'random_projection')` throws `Unknown reduction method`. The upper-casing exists precisely so a lower-case method resolves. | | `.../multimodal/ModalityType.java:78` | A URL ending `.GIF`, `.TIF`, `.AVI`, `.ICO`, `.DIB` or `.SGI` is not detected and falls back to `TEXT`, so an image is embedded as text. | | `ModalityType.java:102` | `supportsExtension("TIF")` and `("AVI")` return `false`. | | `.../remote/doubao/DoubaoModel.java:388` | The payload goes out as `data:ımage/png;base64,...`. `ModalityGroup.IMAGE` is a shipped constant, so no unusual input is needed. | | `nlpmodel/ModelInvocationCacheKey.java:144` | Tokens are lower-cased so equivalent spellings collapse to one key; `provider=openaı`, `modality=ımage`, `format=bınary` break that. | **Six are the same pattern, not reachable today:** `BuiltinFunctions.java:54` (none of the 12 shipped UDF names are altered), `ModalityType.java:60` and `PayloadFormat.java:40` (both feed `equalsIgnoreCase`, which still matches), and `DataValidatorTransformConfig.java:168`/`:336` with `AbstractModel.java:123` (their tokens carry no `i`). Each is one `UNIQUE` or `IN_LIST` label away from breaking. ### SeaTunnel Version dev ### What you expected to happen Case conversion used for matching should not depend on the worker's default locale. The same job should behave identically on every worker. ### Context Reproduced on JDK 11 with `Locale.setDefault(Locale.forLanguageTag("tr-TR"))`. Reverting the fix fails four new tests in `CalciteSQLEngineTest`, `DoubaoMultimodalModelTest` and `ModelInvocationCacheKeyTest`, covering all five reachable sites. ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR. ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
