------------------------------------
Summary: ICUTokenizer might return corrupt tokens due to
concurrency bug in ICU4J
Key: LUCENE-8175
URL: https://issues.apache.org/jira/browse/LUCENE-8175
Project: Lucene - Core
Issue Type: Bug
Reporter: Adrien Grand
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.
