What does this mean exacly? Will it not run with 8.xxx?
At the official oracle site the java runtime version for windows is still at 8.151
and that's the version that I have of course.

Thanks Sander. Looking forward to testing this new version.

Indeed, will not run with 8.xxx. Here you can download version 9:

Thanks for the link. But there is already huge damage done here :(
(not because of your program of course.)

I just noticed that none of my dozens of WB + UCI native java programs installed work anymore probably since the last update 8.151 from 17-10-23. That's a pity.
Sure most here will have the same problem already, but yet unnoticed.

Well, normally they say one should not have several java installations in parallel, but what to do now?
And even if I would try to install an older branch of java again, I guess I have to put the full path in all older installations,
because the system environment variable will be set to the newest one I guess, when calling ''java -jar ....'

User linuxchess compiled a version for Java 8 and announced it at Chess2U:
http://www.chess2u.com/t11492-chess22k
https://drive.google.com/file/d/1fDkS-u ... oXPDLGXnyK

Any idea if this will have some influence on its performance?
(speed - different instructions...)

Probably we can compare nps (if there is only a speed diff) for both?

Can't test this before Thursday though.

What do you mean exactly?
Java 9 is backwards compatible with Java 8 (and +/- same performance), if that is what you are asking.
