While testing Apache Lucene with JDK 18 and JDK 19, we have seen the following crash now quite often (once every few days):

The first crash like this was with 18-ea-b26.
It happens very often with jdk-18 GA release.
But also seen with jdk-19-ea+14.

Not sure how to reproduce this - as always. Looks like the above crash was in Lucene's facet module, so one can try this in a loop:

$ gradlew :lucene:facet:test
