Hi Rory, Apache Wicket build and tests are OK with JDK 16 b28 for both aarch64 and x86_64 (Ubuntu 20.10)!
I had to add --add-opens=java.base/java.io=ALL-UNNAMED to maven-surefire-plugin's JVM arguments because it seems this plugin does not use the (automatic) module name of the Maven project and the JDK sees it as unnamed. And because of this Wicket was not able to install its hooks into Java Serialization API. https://github.com/apache/wicket/commit/b269b6dcc6a7642c5b5211cae60c7fa24dd7e7ef Regards, Martin On Mon, Dec 14, 2020 at 10:18 AM Rory O'Donnell <rory.odonn...@oracle.com> wrote: > Thanks Martin! > > On 14/12/2020 07:46, Martin Grigorov wrote: > > Hi Rory, > > Unfortunately this build breaks Wicket's usage of Serialization API. > public void writeObject(Object streamObj) is not called for some reason > and Wicket cannot intercept the calls. > I will investigate further and update you once I have more details. > > Martin > > On Sun, Dec 13, 2020 at 6:39 PM Rory O'Donnell <rory.odonn...@oracle.com> > wrote: > >> Hi Martin, >> >> *Per the JDK 16 schedule , we are in Rampdown Phase One* *[1] . >> * >> >> *Please advise if you find any issues while testing the latest Early >> Access builds.* >> >> * Schedule for JDK 16 >> o *2020/12/10 Rampdown Phase One* >> o 2021/01/14 Rampdown Phase Two >> o 2021/02/04 Initial Release Candidate >> o 2021/02/18 Final Release Candidate >> o 2021/03/16 General Availability >> * Release Notes [2] >> >> OpenJDK 16 Early Access build 28**is now available at >> http://jdk.java.net/16 >> <https://urldefense.com/v3/__http://jdk.java.net/16__;!!GqivPVa7Brio!Liyl4H4TnxuGbjQuoffXZTV8fQWjpvwYd6e9fjqL1y5xoX5B-5hePKfQDAVawXwBerI$> >> >> * Features - the overall feature set is frozen.
