[jira] [Created] (LUCENE-8933) JapaneseTokenizer creates Token
objects with corrupt offsets
Adrien Grand created LUCENE-8933:
------------------------------------
Summary: JapaneseTokenizer creates Token objects with corrupt offsets
Key: LUCENE-8933
URL: https://issues.apache.org/jira/browse/LUCENE-8933
Project: Lucene - Core
Issue Type: Bug
Reporter: Adrien Grand
An Elasticsearch user reported the following stack trace when parsing synonyms. It looks like the only reason why this might occur is if the offset of a {{org.apache.lucene.analysis.ja.Token}} is not within the expected range.
