--------------------------------------
A release candidate is available for testing:
https://sourceforge.net/p/icu/mailman/message/36259676/. We should give it a
try.

> Key: LUCENE-8175
> URL: https://issues.apache.org/jira/browse/LUCENE-8175
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Adrien Grand
> Priority: Critical
>
> I was digging some test failures with {{testRandomHugeStrings}} that occurred
> since the upgrade to ICU4J 60.2 which happen to boil down to this bug:
> http://bugs.icu-project.org/trac/ticket/13512 which is fixed but not released
> yet.
> In short an int[] is shared across several threads while it shouldn't. As a
> consequence, ICUTokenizer may sometimes return corrupt tokens. I pinged on
> the issue to know when a release fixing this bug is expected.
