I am not sure how to label this change, and whether it needs an entry in the
changelog or not.
Also, once I merged it I should backport it to 9x, correct?

I am doing some performance profiling with Java Flight Recorder (if you
haven't tried it yet, you should, it's awesome!) and am getting diagnostic

It is harmless, it isn't a performance issue really, it only happens at most
once per segment. Exception is the correct mechanism as it is an exceptional
case to bail on processing he

This is during an intensive indexing operation, and it is using a
near-real-time reader created from an IndexWriter. I wonder if we are somehow
in an unusual spot where we

It's also worth noting that we are firing off many small count queries,
rather than executing one large query. So maybe we are visiting all segments
many more times than us

Would a change that at least pre-allocates a single exception instance,
rather than making a new one every time, be welcome / desired?

You are doing count queries that get implemented with Weight.count().
Separately, that's really strange, i dont know what you are doing, but that
isn't very typical. e.g. if you are j

Also, when using this flightrecorder tool, to help reduce noise you need to
pass a few flags (e.g. `DebugNonSafepoints`) or you WILL see a ton of ghosts,

Our current use case involves doing a number of existence-tests of boolean

ok, thanks for the explanation. `BooleanWeight.count` can only help in "rare
cases" IMO here, but it isn't rare enough in your measurements (e.g. maybe for

which inhibits JVM optimization for exception stack traces. So that probably
