What problem are you facing?

The driver does not retry commitTransaction nor abortTransaction when the error code is not retryable but RetryableWriteError label is present.

From the spec:

abortTransaction is a retryable write command. Drivers MUST retry once after abortTransaction fails with a retryable error according to the Retryable Writes Specification, regardless of whether retryWrites is set on the MongoClient or not.

commitTransaction is a retryable write command. Drivers MUST retry once after commitTransaction fails with a retryable error according to the Retryable Writes Specification, regardless of whether retryWrites is set on the MongoClient or not.

What driver and relevant dependency versions are you using?

4.x driver, I believe this impacts 3.x as well.

Steps to reproduce?

Run these spec tests:

• abortTransaction only retries once with RetryableWriteError from server
• abortTransaction does not retry without RetryableWriteError label
• commitTransaction does not retry error without RetryableWriteError label
• commitTransaction retries once with RetryableWriteError from server
