Sanne & Yoann, I’m happy to announce that moving forward Oracle’s Java DevRel Team will manage the Quality Outreach Program. I would like to thank Rory for all the efforts he's put into this program and wish him all the joy and happiness that retirement can bring! We have big shoes to fill but we’re excited to continue building off the amazing structure Rory has put in place.
The JDK 18 schedule is now known [1] with a feature freeze date (Rampdown Phase One) less than 4 weeks away! This time, we have 2 important heads-ups, one related to JEP 411 (Deprecate the Security Manager for Removal), and one related to JEP 416 (Reimplement Core Reflection with Method Handles). We're asking your help to test and confirm that your project works seamlessly now that those 2 JEPs are integrated in the JDK 18 Early-Access builds. [1] https://openjdk.java.net/projects/jdk/18/ # JEP 411 - Deprecate the Security Manager for Removal Starting JDK 18 b21 [2], the default value of the 'java.security.manager' system property is set to "disallow". This means that any application or library that enables the Security Manager by calling `System.setSecurityManager` will now have to specify `-Djava.security.manager=allow` on the command-line in order for that code to continue working as expected. This change was originally targeted for JDK 17, but after some discussion/feedback from the community, the change was delayed until JDK 18 [3]. [2] https://bugs.openjdk.java.net/browse/JDK-8270380 [3] https://openjdk.java.net/jeps/411#Description # JEP 416 - Reimplement Core Reflection with Method Handles JEP 416 [4] reimplements `java.lang.reflect.Method`, `java.lang.reflect.Constructor`, and `java.lang.reflect.Field` on top of `java.lang.invoke` method handles. Making method handles the underlying mechanism for reflection will reduce the maintenance and development cost of both the `java.lang.reflect` and `java.lang.invoke` APIs. This is solely an implementation change but we encourage you to test your project to identify any behavior or performance regressions.
