You can see their `toString` method in all xxx.java in `clients/src/generated/java` directory. For fields of type String, the `toString()` method is still called, which brings an unnecessary method call. example: AddOffsetsToTxnRequestData#toString() `@Override public String toString() { return "AddOffsetsToTxnRequestData(" + "transactionalId=" + ((transactionalId == null) ? "null" : "'" + transactionalId.toString() + "'") + ", producerId=" + producerId + ", producerEpoch=" + producerEpoch + ", groupId=" + ((groupId == null) ? "null" : "'" + groupId.toString() + "'") + ")"; } ` In fact, `transactionalId` and `groupId` are already String types. -- This is an automated message from the Apache Git Service.
