The following JEP is proposed to target JDK 28: 539: Strict Field Initialization in the JVM (Preview) https://openjdk.org/jeps/539 Summary: Introduce strictly-initialized fields in the Java Virtual Machine. Such fields must be initialized before they are read, thus default values such as 0 or null are never observed. For strictly-initialized fields that are final, the same value is always observed. This is a preview VM feature, available for use by compilers that emit class files. Feedback on this proposal from JDK Project Committers and Reviewers [1] is more than welcome, as are reasoned objections. If no such objections are raised by 23:00 UTC on Thursday, 30 July, or if they’re raised and then satisfactorily answered, then per the JEP 2.0 process proposal [2] I’ll target this JEP to JDK 28. - Mark [1] https://openjdk.org/census#jdk [2] https://cr.openjdk.java.net/~mr/jep/jep-2.0-02.html
