The Gen product team are still hoping to provide the JDK 17 & 21 Support by the end of this calendar year. However, that is still subject to the statement at the top of the above page i.e.
"This is a forward-looking statement. This is subject to change at any time without notice. The development, release, and timing remain at Broadcom's sole discretion."
