RFR: 8249079: LambdaFileEncodingSerialization.java failed "exitCode = 1 expected [true] but found [false]"

Tue Jul 14 12:26:49 UTC 2020

Thanks Christoph,
I am fairly sure the problem occurs due to the test spawned javac Process 
not having the correct LANG encoding to support the UTF-8 class name 
characters, hence why this patch sets the full set of LC_ALL, LANG and 
LANGUAGE, as I am suspecting on some machines where the hosting 
environment might have these set differently. Your Jenkins links are 
useful thanks.
If it is still an issue, then I think I will need to remove the test and 
re-think how to verify the use case, which we discovered on our z/OS port 
where the default file encoding is EBCDIC.
Appreciate your help
Thanks
Andrew

Hi Andrew,

we’ve had this error in our latest CI builds for Sapmachine/OpenJDK 16:
https://ci.sapmachine.io/view/Pull%20Request%20Validation%20Builds%20/job/build-16-pr-validation-linux_x86_64/6/
https://ci.sapmachine.io/view/Pull%20Request%20Validation%20Builds%20/job/build-16-pr-validation-linux_ppc64le/5/

Furthermore we saw some probably related issue here:

I’m currently retrying to see if we can reproduce this. If so, I’m willing 
to try your patch…

Cheers

Is anyone able to help review and test this please? 
Can anyone tell me if the problem is still failing? 
I have been unable to recreate in my environment having run several 100 
iterations. I am hoping this webrev might cover the machine specific 
issue. 

Many thanks

Hi Vicente, 
Would you be able to review, perform a submit test and merge this fix 
please? 
I am suspecting the intermittent test failure is due to a specific test 
machine LANG/locale setup, which I know will produce the mentioned 
failure. 
I have added setting LANG & LANGUAGE to the test spawned javac Process, 
which I think should have been set.
