This JEP allows a target switch expression to be tested against a number of patterns, each with a specific action, allowing complex data-oriented queries to be expressed concisely and safely. JEP 420, Pattern Matching for switch (Second Preview), has been promoted from Candidate to Proposed to Target for JDK 18. The review for JEP 419 concludes on November 23, 2021. Changes in this second incubator include: support for more carriers in memory access var handles such as boolean and MemoryAddress interface a more general dereference API for the MemoryAddress and MemorySegment interfaces a simpler API to obtain downcall methods handles such that passing a MemoryType enumeration is no longer necessary and a new API to copy Java arrays to and from memory segments. This JEP evolves the first incubator, JEP 412, Foreign Function & Memory API (Incubator), delivered in JDK 17, to incorporate improvements based on Java community feedback. JEP 419, Foreign Function & Memory API (Second Incubator), has been promoted from Candidate to Proposed to Target for JDK 18. This week's Java roundup for November 15th, 2021, features news from OpenJDK JEPs, JDK 18, Project Loom, numerous point releases on Spring projects, MicroProfile 5.0-RC2, Payara Platform, a proposed new Jakarta EE specification, JHipster 7.4.0, TornadoVM 0.12, Apache Camel K 1.7 and Kotlin 1.6.0.
