Hello Community,

I am an engineer from Amazon Product Search and we recently encountered
a WrongThreadException in our service when building TermStates with
Lucene9.6 and JDK19.02+9.


We are just using one thread when initializing term states. I am wondering
if any other users encounter this problem, is this a known bug/issue of
JDK19?
