Rollback fail: "transaction already initiated" but also "no transaction found"

[tekhedd]

I don't know if it's a failure of the protocol or the backend, but after a failed DELETE followed by a rollback, I am told both that I already have an open transaction and also that I do not.

** What I did **

client.beginTransaction();
client.sqlExec("DROP TABLE nonexistent"); // throws

Catch the "table does not exist" error and attempt to roll back. Rollback fails with INVALID_ARGUMENT: no transaction found.

client.beginTransaction(); // throws!

Catch this error, IllegalStateException: transaction already initiated. Attempt to roll back, which fails with "no transaction found."

So, I have a transaction but I don't? I assume the workaround is to just close the client completely.

This is in Java on linux running against a docker container.
