We have an imperial tonne of automata hitting us and this is perfectly plausibly the source of the ZRR. Create a UDF class designed to detect this automata.
Note to future self or future @Ironholds, depending on who claims this task:
uap-java currently fails to build due to uap-core updates. A user has created a pull request (https://github.com/ua-parser/uap-java/pull/7) that fixes the problems (all tests pass, uap-java builds with the proposed change) but the PR is yet to be merged by an uap-java admin.
