I find when running with -XX:TieredStopAtLevel=1 and ZGC enabled it
fails when running with Lucene's indexing demo
"org.apache.lucene.demo.IndexFiles" or SPECjbb2015.
I tried javac, and other simple examples, but I haven't managed to
find anything simple that provokes the issue.
I've uploaded this here:
If you have the appropriate java command on your patch, if you run
"index.sh" with a directory of files index as the parameter, it will
reproduce the problem.
