Bruno Roustant commented on LUCENE-9241:
----------------------------------------

I reviewed the patch. Sounds good to me.

I was wondering if the change in ByteRunAutomaton could impact perf. I don't 
think so, but I'm going to run a couple of benchmarks.

Similarly in LUCENE-9245 I'll change AutomatonTermsEnum to reduce memory in 
case of large automaton.

> Currently each test jvm has Xmx of 512M. With a modern macbook pro this is 
> 4GB which is pretty crazy.
> On the other hand, if we fix a few edge cases, tests can work with lower 
> heaps such as 128M. This can save many gigabytes (also it finds interesting 
> memory waste/issues).
