OpenJDK
JEP 421, Deprecate Finalization for Removal, has been promoted from Candidate to Proposed to Target status for JDK 18. This JEP deprecates the finalization mechanism, first introduced in JDK 1.0, for removal in a future JDK release. While finalization was designed to avoid resource leaks, it suffered several critical flaws such as unpredictable latency, uncontrolled behavior and threading, and was always enabled by default. The review for JDK 421 concludes on December 7, 2021.
JDK 18
Build 26 of the JDK 18 early-access builds was made available this past week, featuring updates from Build 25 that include fixes to various issues. More details may be found in the release notes.
The feature set for JDK 18 currently stands as follows:
- JEP 400: UTF-8 by Default
- JEP 408: Simple Web Server
- JEP 413: Code Snippets in Java API Documentation
- JEP 416: Reimplement Core Reflection with Method Handles
- JEP 417: Vector API (Third Incubator)
- JEP 418: Internet-Address Resolution SPI
- JEP 419: Foreign Function & Memory API (Second Incubator)
- JEP 420: Pattern Matching for switch (Second Preview)
- JEP 421: Deprecate Finalization for Removal (Proposed to Target)
Developers are encouraged to report bugs via the Java Bug Database.
