You can enable the profile explicitly, but it is activated by default when `CI=true`. Admittedly, picking a less implicit trigger would have been a better choice.

Our test compares Log4j's output to the live JVM's `printStackTrace()` output, so it only passes on 8u272 or newer. My local JDK is 1.8.0_482, which is why it passes for me; you must be running an older 8u build. Piotr
