Java Development Kit 19, due this September, now has a second feature officially proposed to target it: A vector API to express vector computations, which would undergo a fourth incubation in the next Java release. The other proposed feature is a port of the JDK to the open source Linux/RISC-V instruction set architecture (ISA).
JDK 19, or simply Java 19, potentially could host a vast number of features, ranging from universal generics to value objects, according to plans under way for enhancing Java. But so far, the vector API and the RISC-V port are the only officially proposed features to target JDK 19. JDK 19 would follow JDK 18, which arrived March 22. Standard Java is on a six-month release cadence.
