### Purpose `FormatBatchWriteBuilder.newWriteSelector()` delegated to `table.newBatchWriteBuilder().newWriteSelector()`, but a `FormatTable`'s batch write builder is `FormatBatchWriteBuilder` itself, so the call rebuilt the same builder and re-entered the same method. Every invocation recursed without a base case and failed with a `StackOverflowError`. Format tables have no bucket or write selection, so the builder now returns `Optional.empty()`, which the `WriteBuilder` contract defines as "no data distribution is required" and which matches the answer the file-store builder gives for bucket-unaware and postpone modes. ### Tests Adds `FormatTableCompatibilityTest.testNewWriteSelectorIsEmptyInsteadOfRecursing`, which pins `newBatchWriteBuilder().newWriteSelector()` to an empty `Optional` so the recursion cannot come back. ### API and Format No. ### Documentation No. -- This is an automated message from the Apache Git Service.
