Description

It is a tokenfilter, tries to change offsets, so of course TestRandomChains finds bugs in it:

NOTE: reproduce with: gradlew test --tests TestRandomChains.testRandomChains -Dtests.seed=12BC606B774693E4 -Dtests.nightly=true -Dtests.slow=true -Dtests.locale=om-Latn-ET -Dtests.timezone=Australia/Yancowinna -Dtests.asserts=true -Dtests.file.encoding=UTF-8
