-------------------------------------
Summary: Possible bug in StemmerOverrideFilter / FST
Key: LUCENE-6977
URL: https://issues.apache.org/jira/browse/LUCENE-6977
Project: Lucene - Core
Issue Type: Bug
Components: modules/analysis
Affects Versions: 5.4
Reporter: Markus Jelsma
Priority: Minor
Fix For: 5.5
Attachments: LUCENE-6977.patch
We ran across an issue in a custom token filter that like the
StemmerOverrideFilter relies on the FST. The issue is reproducible in the
StemmerOverrideFilter. I am not sure whether it is a real problem in the FST.
Attached a patch with a unit test that is going to fail. It uses random input
with some code from commons-lang3.
