zhangshenghang opened a new issue, #12522: URL: https://github.com/apache/seatunnel/issues/12522
### Description `new SeaTunnelRowType(fieldNames, fieldTypes)` stores the caller's arrays by reference (`this.fieldNames = fieldNames`). `SeaTunnelRowType` is treated as an immutable type definition, but any later mutation of the caller's arrays silently changes the row type (field names, types, and every `indexOf` lookup) for everything that already holds the type. Expected: the constructor should copy the arrays so the type definition cannot be changed externally after construction. ### Impact Latent correctness bug: callers that reuse/mutate the arrays they passed in (common in builders and loops that build many row types) corrupt already-created types. -- This is an automated message from the Apache Git Service.
