JSR 395, Java SE 20, was submitted this past week to formally announce the six-member expert group for JDK 20, namely Simon Ritter (Azul Systems), Jayaprakash Arthanareeswaran (Eclipse Foundation), Andrew Haley (Red Hat), Christoph Langer (SAP SE), Iris Clark (Oracle) and Brian Goetz (Oracle). Clark and Goetz will serve as the specification leads. Other notable dates at this time include a public review from December 2022 through January 2023 and the GA release in March 2023.
