1. JEP 350 – Dynamic CDS Archives: Extends application class-data sharing to allow the dynamic archiving of classes at the end of Java application execution. The archived classes will include all loaded application classes and library classes that are not present in the default, base-layer CDS archive.
2. JEP 351 – ZGC: Uncommit Unused Memory: Enhances the z garbage collector to return unused heap memory to the operating system.
3. JEP 353 – Reimplement the Legacy Socket API: Replaces the underlying implementation used by the java.net.Socket and java.net.ServerSocket APIs with a simpler and more modern implementation that is easy to maintain and debug. The new implementation will be easy to adapt to work with user-mode threads, a.k.a. fibers, currently being explored in Project Loom.
4. JEP 354 – Switch Expressions (Preview): Extends switch so it can be used as either a statement or an expression, which will simplify everyday coding, and prepare the way for the use of pattern matching (JEP 305) in switch.
5. JEP 355 – Text Blocks (Preview): Adds text blocks to the Java language, which will simplify the task of writing Java programs by making it easy to express strings that span several lines of source code, while avoiding escape sequences in common cases; enhance the readability of strings in Java programs that denote code written in non-Java languages; as well as support migration from string literals by stipulating that any new construct can express the same set of strings as a string literal, and interpret the same escape sequences, and be manipulated like a string literal.
