The PreConfiguredTokenFilter#singletonWithVersion uses the version internaly for the token filter factories but it registers only one instance in the cahce and not one instance per version. This can lead to exceptions like the one described in elastic#50734 since the singleton is created and cached using the version created of the first index that is processed. Remove the singletonWithVersion() methods and use the elasticsearchVersion() methods instead. Fixes: elastic#50734 (cherry picked from commit 24e1858)
