Description

Problem: ci fails on PR#18606 - unrelated to (1), this issue reads Unable to execute HTTP request: Trying to access closed classloader and seems unrelated to the code change (effectively a 1 line Thread.sleep ). This means it is an intermittent issue affecting the KDF feature more widely, and has not yet been picked up by the 20+ runs on the ci. Not reproducible locally. Intermittently failing on ci, frequency unknown, likely more than 20 : 1. Resolution: unknown.
