Some tests using provided executors are randomly failing in pipeline.

🐞 Bug Report

Current Behavior

There are few tests that are randomly failing in pipeline. (~1-2 failures in 1000 runs) All are using provided executors. There is obviously race condition somewhere, but it's not easy to catch. Probably not going to fix that unless smb else will raise it as a problem.

Steps to Reproduce

• Search for tests that have @Retry annotation.
• Remove Retry.
• Add Shampoo rule @Rule public final TestRule shampoo = new ShampooRule(1000); to class with failing tests
• Run Test, it will be repeated up to 1000 times or until failure.

Expected Behavior

Tests should not fail.
