Java Gateway, Java version?

So, I needed to start Java Gateway, and found, that it does not want to work with the latest Java versions, I tried 20, 18, 17

Start External Language Server %Java Server:

Please wait...result will show below:

2023-07-26 19:46:24  Starting Java Gateway Server '%Java Server'
2023-07-26 19:46:24  *ERROR* Return from RunStartCmd: ERROR #5049: Java version '' is not supported.
2023-07-26 19:46:25  An error occurred while trying to start the Gateway Server External Language Server failed to Start:
ERROR #5049: Java version '' is not supported.

Error, only says, that it will not work, and say nothing, about which version it wants to seeI finally managed to start it with version 11, but I had to try multiple latest versions 

So, IRIS in 2023, does not want to work with the latest LTS version 17, which is from 2021, almost 2 years ago. And only accepts version 5 years old?

Product version: IRIS 2023.2

Documentation shows that Java 8 and 11 are supported.

11 support was added briefly before Java 17 LTS was released (early 2021 I believe), but it seems InterSystems' Java support has not been updated in the past 2 years. This is something we are working on, however I don't know when that change might be released.
