Any plan for Java 19up and Loom (virtual thread) ?

[Guy deffaux]

Hello L7 team

Can you share your plan to move from the recently adopted Java 17 (GW v11.1, noting that Java 17 was released Sept. 2021) to 21 LTS or higher, and if you have target to leverage the new Loom project virtual thread model ?

With the current way of the thread model, the gateway can get saturated very easily when a heavily used back-end gets slow. Threads are waiting, CPU is low, queue may happen in front of the gateway, preventing other APIs to be executed. Only CPU and RAM should be limiting factors of the GW, not a slow back-end!

The new virtual thread model will very likely make things so much better than the current situation... 

Thank you very much.

Hello Guy,

We do plan to upgrade to JDK21 in our 11.2 release currently planned for October 2025.

We do not have a plan to adopt a new thread model at the same time, but it is something we can consider as a future enhancement.
