Found (encountered) another JDK 16 problem with Apache Geode (see StackTrace below).
Setting another (--add-opens JVM option to 'java.base/java.util=ALL-UNNAMED') resolves this issue for now. 2021-05-10 15:10:25,458 ERROR xecutors.LoggingUncaughtExceptionHandler: 92 - Uncaught

Thanks Bill (everyone) for the information. For clarification, SDG primarily builds on Apache Geode GA versions (e.g. 1.13.2). This is true for 3rd party libs as well. We rarely, if ever, use milestones or release candidates, much less snapshots, for any non-controlled dependency, in the mainline. This is necessary to always keep SD[G] in a releasable state when/if needed (e.g. critical CVE). As an exception, we additionally build SDG (master-next) on the most recent 1.14 snapshots (i.e. mainline version +1, e.g. main is set to 1.13 [1] and master-next is set to 1.14 [2], even if an Apache Geode 1.15 branch were cut) to prepare SDG for the next version when it becomes GA so we are ready to upgrade to that version and get it into a release ASAP. All of this is to say, any changes to support JDK 16 or above, would need to be either in a Geode 1.13.3+ release and/or 1.14 when available for SDG to be fully JDK 16+ compatible.

John, this doesn't speak to the general question of JDK version support. But the particular stack trace you showed makes me wonder if the fix for GEODE-9081 (landed on 3/30/21 on the develop branch) might get you a little bit further. That commit 7ac9d7e4f0d04c99298067ca0611d9326e96d9cf eliminated the reflective field access in favor of some simpler down-casting.

The Spring Data Team is currently looking ahead towards Java 16 when building and running Spring Data examples to get a sense for what works and what doesn't, now that Java 16 is GA along with anticipation for users with questions or problems. Spring Framework itself aligns and is based on LTS Java versions only, currently Java 8 with Spring Framework 5. Spring Framework 6 will likely move the baseline to Java 11 or possibly even Java 17, we are not sure which yet. Just want to share our findings and give advanced notice.

Thanks for reporting this John. The next LTS version of Java (17) is due later this year. I think Geode needs to at least support every LTS version of Java and clearly we would need to fix errors like this. Do you see a need to support Java 16 now?
