distroless/java and filename encoding to UTF-8

[npierot06]

Hello all, It seems that in the latest distroless/java:11, the sun.jnu.encoding is back to ANSI_X3.4-1968 instead of UTF-8 when using LANG=C.UTF-8

I tried 3 different images :

• FROM gcr.io/distroless/java:11 : causes an error in filename encoding
• FROM gcr.io/distroless/java@sha256:2d96a9a913bf3923f504dca3e91260371591bac0e679d30a9ab19cece86dcf25 : causes an error in filename
• FROM gcr.io/distroless/java@sha256:d9cceee40b4ffa4418793fad0400948205ed59fd24df4740ba6fa74562eff16f : works fine

Fo now I can deal with the working sha256, but it would be great if the same fix done for https://github.com/GoogleContainerTools/distroless/issues/253 would be applied in future releases

Here is a test case to reproduce test.zip docker build -t test . && docker run --rm test

Thanks for all

Hi again, maybe zip file is not appropiated here :)

here are the files : A.java :

public class A { public static void main(String... args) { System.out.println("file.encoding=" + System.getProperty("file.encoding")); System.out.println("sun.jnu.encoding=" + System.getProperty("sun.jnu.encoding")); System.out.println("java.version=" + System.getProperty("java.version")); System.out.println("LANG=" + System.getenv("LANG")); System.out.println("\u65E5"); } }

Dockerfile :

FROM gcr.io/distroless/java:11

FROM gcr.io/distroless/java@sha256:2d96a9a913bf3923f504dca3e91260371591bac0e679d30a9ab19cece86dcf25
