Bug#1004950: reprotest fails when using kk_KZ.RK1048 locale with java (locale not supported by java)

[Fab Stz]

Package: reprotest
Version: 0.7.16
Severity: normal

Dear Maintainer,

I have a CI job that runs reprotest. The project, at some time, makes calls to
java. However this fails/crashes sometimes.

By narrowing things down it always crashes when locale kk_KZ.RK1048 is in use.

By searching further I discovered that kk_KZ.RK1048 locale/charset is not 
supported by java [1]. Hence the crash:

$ LC_ALL=kk_KZ.RK1048 java -version
Error occurred during initialization of VM
java.lang.IllegalArgumentException: Null charset name
        at java.nio.charset.Charset.lookup(java.base/Charset.java:455)
        at java.nio.charset.Charset.defaultCharset(java.base/Charset.java:608)
        at java.lang.StringCoding.decode(java.base/StringCoding.java:316)
        at java.lang.String.<init>(java.base/String.java:592)
        at java.lang.String.<init>(java.base/String.java:614)
        at java.lang.System.initProperties(java.base/Native Method)
        at java.lang.System.initPhase1(java.base/System.java:1948)



$ LC_ALL=C java -version
openjdk version "11.0.12" 2021-07-20
OpenJDK Runtime Environment (build 11.0.12+7-post-Debian-2)
OpenJDK 64-Bit Server VM (build 11.0.12+7-post-Debian-2, mixed mode, sharing)


Expected behavior? That it works also with call to java? or maybe an option to
disable this locale if java is used?
