Apache jenkins failed with:
```
Build timed out (after 60 minutes). Marking the build as aborted.
[ERROR] Failed to execute goal

VM terminated without properly saying goodbye. VM crash or System.exit called?
```
The last thing in the console before that was the log below (looks like it
hung when trying to execute `YamlRollingTimeWindowMeanEnricherTest` - hard to
tell if that was the test's fault or the environment's fault):
```
