Robert Muir commented on LUCENE-5468:
-------------------------------------
Well, I don't want the whole issue to get hung up on that stuff. Basically i'm
working on a number of changes (especially tests though, to ensure the stuff is
really working correctly). If we want, we can just lay down my new files on top
of the existing stuff, or we can keep it/deprecate it, whatever we want to do.
I just want to make some progress on a few improvements I've been investigating
to try to make this thing more usable :)
> Hunspell very high memory use when loading dictionary

> Key: LUCENE-5468
> URL: https://issues.apache.org/jira/browse/LUCENE-5468
> Project: Lucene - Core
> Issue Type: Bug
> Affects Versions: 3.5
> Reporter: Maciej Lisiewski
> Priority: Minor
> Attachments: patch.txt
>
>
> Hunspell stemmer requires gigantic (for the task) amounts of memory to load
> dictionary/rules files.
> For example loading a 4.5 MB polish dictionary (with empty index!) will cause
> whole core to crash with various out of memory errors unless you set max heap
> size close to 2GB or more.
> By comparison Stempel using the same dictionary file works just fine with 1/8
> of that (and possibly lower values as well).
> Sample error log entries:
