> Key: LUCENE-9930
> URL: https://issues.apache.org/jira/browse/LUCENE-9930
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Alan Woodward
> Assignee: Alan Woodward
> Priority: Major
> Fix For: main (9.0)
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Large static data structures should be loaded in Analyzer constructors and
> shared between threads, but the UkrainianMorfologikAnalyzer is loading its
> dictionary in `createComponents`, which means it is reloaded and stored on
> every new analysis thread. If you have a large dictionary and highly
> concurrent indexing then this can lead to you running out of memory as
> multiple copies of the dictionary are held in thread locals.
