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

[Langer, Christoph]

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:
https://ci.sapmachine.io/view/Pull%20Request%20Validation%20Builds%20/job/build-16-pr-validation-linux_ppc64/6/
ERROR: Cannot delete workspace :Malformed input or input contains unmappable characters: /home/jenkins/slave-home/workspace/build-16-pr-validation-linux_ppc64/test_report_jdk/JTwork/scratch/0/TestLambdaFileEncodingSerialization$ABC������.class
Error when executing cleanup post condition:
hudson.AbortException: Cannot delete workspace: Malformed input or input contains unmappable characters: /home/jenkins/slave-home/workspace/build-16-pr-validation-linux_ppc64/test_report_jdk/JTwork/scratch/0/TestLambdaFileEncodingSerialization$ABC������.class
                at hudson.plugins.ws_cleanup.WsCleanup.perform(WsCleanup.java:242)

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

Cheers
Christoph

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.
