Mark Miller commented on SOLR-8539:
-----------------------------------
It is hard to guarantee, but well behaving code should be careful when catching
Errors and let OOMExceptions bubble out I think. It's the only way for the Java
kill on OOM feature to work at all.
We may find that some other code in some other lib is swallowing Errors and not
letting OOMException bubble up, but in that case I think we would follow the
same procedure and file a bug with that component.
