Commit 6bba35a7096ef2d4023ba9339e9cc30268d520ce in lucene-solr's branch
refs/heads/master from Bruno Roustant
[ https://gitbox.apache.org/repos/asf?p=lucene-solr.git;h=6bba35a ]
LUCENE-9286: FST.Arc.BitTable reads directly FST bytes. Arc is lightweight
again and FSTEnum traversal faster.
> FST arc.copyOf clones BitTables and this can lead to excessive memory use

> I see a dramatic increase in the amount of memory required for construction
> of (arguably large) automata. It currently OOMs with 8GB of memory consumed
> for bit tables. I am pretty sure this didn't require so much memory before
> (the automaton is ~50MB after construction).
> Something bad happened in between. Thoughts, [~broustant], [~sokolov]?
