If this PR shows conflicts, here are instructions to help rebasing this work branch after reformat at 814a919:

git rebase c845f509770e38aa9663a97cb2f9bcd3e5d39e28
git rebase --strategy-option=theirs --exec 'pre-commit run --from-ref HEAD~ --to-ref HEAD' 814a9190ff60af86086e8d111660146569ef6e19
git rebase develop

The last rebase should be omitted if another reformat has happened (similar instructions should be followed for rebase over next reformat).

See more details at Activiti/Activiti#4277.
