*Due in March 2022, Java 18 has attracted recommendations to hatch the vector API, preview pattern matching for switch statements, and embrace UTF-8 as the default character set. *
Due in March 2022, Java 18 keeps on adding highlights, with nine component recommendations being considered for it up until this point, including the deprecation of finalization, a capability that was intended to help avoid resource leaks but has brought with it risks of unconstrained behavior and unpredictable latency.
The OpenJDK page for Java Development Kit (JDK) 18 records the accompanying elements as authoritatively focusing on JDK 18 as of November 24: a service provider interface, a basic web server, a vector API, code snippets, a reimplementation of core reflection, a UTF-8 charset, the second incubator of a foreign function and memory API, and the second preview of pattern matching for switch statements. Deprecation of finalization is proposed to target JDK 18 in the JDK Enhancement Proposal (JEP) record.
