Java problem!

[Guenther]

Just today I noticed that none of my native WB/UCI java chess programs works anymore here.
My guess is that since the latest update 8.151 (Oct 23), which will be replaced by java 9 soon anyway, they won't be executed anymore.
Can someone confirm this with 8.151?

My engines with 64-bit 8.151 work OK.

Really the native only engines? Just jar no Jet compiles or whatever (e.g. NOT Bagatur)

Like Gabor, I have no problems running Java based engines (Chess22k 1.5, Frittle 0.4, Bagatur 1.5e, all jar versions) with the 64 bit version of Java 1.8.0_151. I am curious, are you using the 32 bit version, Guenther? And are the programs remaining in memory, or simply crashing and exiting?

They simply don't load Tony.
I have Java 32 and 64 bit installed.

Oops I have a strange idea now! For more systematic naming in my installations and for my batch, which creates automatically a json file
from my wb.ini for use in cute/cute-cli I renamed some paths to engine folders e.g. .\Engines\JAVAWB to ...\WBJAVA and same for UCI.
May be the prefetch harms here!? I will check and delete all prefetch data.

Well that idea was too weird and did not help :(
WB2UCI simply says 'died on me' and Polyglot says 'file not found' despite it is there. No idea what this can be w/o any further change than path renaming a while ago. (even tried full paths, but did not help)

My first suspicion was correct. After uninstalling all Java 8.151 installations and reinstalling 8.u141 from July
(I found a tech site offering older java archives with a simple download - unlike oracle, which also had archives
of older versions for testing, but asked for registration and practically a full biography with at least 12 mandatory fields
e.g. phone number at work at home etc....disgusting for a free download of an old thing), all java native programs work again!

Except the new Chess22k 1.6 of course ;-)

It seems java 8.151 on WIN7 behaves different otherwise I don't understand why both of you, if really tried plain jar files, don't have this problem.

Maybe it does have something to do with the OS then. I have Windows 10.

With Java 9 all will get this problem though. Already googling about the
best way using 2 parallel installations.

Which engine does not work properly with Java 9? Let me have a look.
(and maybe it is better to ask java related questions in this topic instead of the chess22k 1.6 topic)

All java native engines did not work already with 8.151 here on my machine with WIN7, like I said already in the beginning of this thread.

Both Carballo and Fischerle (jar-files) work just fine on my pc using Java 9 with Windows 7.
