ROLLBACK when commit on failed transaction?

[IvyDev0]

I'm submitting a ...

• bug report
• feature request

Describe the issue
commit() doesn't throw any exceptions/rollback when the transaction has failed

Driver Version?
REL42.2.9

Java Version?
11

PostgreSQL Version?
10.7

To Reproduce

connection.setAutoCommit(false); // start transaction
execute("SELECT pg_sleep(20)")); // our timeout here is set to 10, so we got "canceling statement due to user request", expected
execute("SELECT 0")); // since the last statement failed, here we got "current transaction is aborted", expected

connection.commit(); // it finished without any exceptions. 

1. Shouldn't the driver ROLLBACK if there's an error? (I couldn't find anything about it in the code)
2. Why can I still commit?

Or it's designed to let the users to rollback ourselves?

Thanks.
