[hibernate-dev] Re: JDK 16 is in Rampdown Phase One

[Yoann Rodiere]

Hello Rory,

We did experience problems related to JDK 16 denying illegal accesses
across modules, but they were either in Gradle [1] or in components we use
for tests only. Either way, a few --add-opens did the trick, and these
problems aren't caused by Hibernate.

Hibernate ORM: Tested with version 5.5.0-SNAPSHOT. Everything works fine
with JDK 16 EA build 28.
Hibernate Validator: Tested with versions 6.1, 6.2 and 7.0. Everything
works fine with JDK 16 EA build 28.
Hibernate Search: Tested with versions 5.11 and 6.0. Everything works fine
with JDK 16 EA build 28.
Hibernate Reactive: Tested with version 1.0. Everything works fine with JDK
16 EA build 28.
