JDK 18/Java 18 was released last month , and JDK 19 is scheduled to be released in September this year. A few days ago, the official proposed two features that will be launched in the next version. One is the Vector API and the other is the porting of the JDK to RISC-V. Among them, the former Vector API is an API for expressing vector computing, which will be hatched for the fourth time in the next Java version ; the latter proposed function is to port the JDK to the open source Linux/RISC-V instruction set architecture (ISA).
Although JDK 19 may carry a large number of features, such as generic generics, value objects and record mode, so far, only two features have been officially proposed for JDK 19: Vector API and porting to RISC-V.
In the details of JEP 422, the official writes:
RISC-V is a free and open source RISC Instruction Set Architecture (ISA), originally designed at the University of California, Berkeley, and now collaboratively developed under the auspices of RISC-V International. It is already supported by a wide range of language toolchains. With the increasing popularity of RISC-V hardware, JDK porting will be valuable.
But the official said that the Linux/RISC-V porting will only support the RV64GV configuration of RISC-V, which is a general-purpose 64-bit ISA. Support for other RISC-V configurations, such as a generic 32-bit configuration (RV32G), will be considered in the future.
According to the official release schedule, JDK 19 will have a GA release on September 20, followed by the Rampdown phases on June 9 and July 21, and release candidates on August 11 and August 21 .
Like JDK 18, JDK 19 will also be a short-term release with only six months of support. The latest LTS version is JDK 17 released on September 14, 2021, and the next LTS version will be JDK 21 released in September 2023.
