Hey, Our team at Amazon Product Search recently ran our internal benchmarks with JDK 17. We saw a ~5% increase in throughput and are in the process of experimenting/enabling it in production. We also plan to test the new Corretto Generational Shenandoah GC.
On a side note, the Lucene codebase still uses the deprecated (as of JDK17) AccessController in the RamUsageEstimator class. We suppressed the warning for now (based on recommendations <http://mail-archives.apache.org/mod_mbox/db-derby-dev/202106.mbox/%3cjira.13369440.1617476525000.615331.1623951480...@atlassian.jira%3E> from the Apache Derby mailing list). - Gautam Worah.
