when run as part of the downstream build from CI in the cedar repository. This presumably impacts a local build, but I have not tried to reproduce. Likely related to most recent commit to the 3.4.x release branch #241 which did touch the formatter tests.

The difference is just a missing trailing new line in the actual output, so the fix is probably just to update the expected output to remove it, but we should first check that no trailing new-line is the expected output and there isn't something funny happening that might cause a new line to be lost in the JNI layer.
