JavaSyntax7CompilationTest fails in a non-English environment

[satob]

Problem

When you run mvn test on a non-English environment, the test JavaSyntax17CompilationTest.testInstrumentationAndCompilation_17_NonReifiableTypes will fail with the following error:

-------------------------------------------------------------------------------

Solution

Setting -Duser.language=en to JAVA_TOOL_OPTIONS fixes this problem.

Note

The following workarounds didn't work for me:

1. Add -DargLine option like mvn -DargLine="-Duser.language=en" test
2. Add <user.language>en</user.language> to <configuration> of maven-compiler-plugin

I struggle reproducing it. What exact Java version do you use and what language setting do you use and where is it configured (operating system, JAVA_OPTS, ...)?

[satob]

I had reproduced the problem with OpenJDK 17.0.9 on Windows 11 version 22H2 (Build 22621.2428) Japanese environment.

• The output of java --version is like this:

openjdk 17.0.9 2023-10-17
OpenJDK Runtime Environment Temurin-17.0.9+9 (build 17.0.9+9)
OpenJDK 64-Bit Server VM Temurin-17.0.9+9 (build 17.0.9+9, mixed mode, sharing)

• The output of Get-WinSystemLocale is like this:

LCID             Name             DisplayName
----             ----             -----------
1041             ja-JP            日本語 (日本)

• JAVA_OPTS is empty.

Thank you! I've been testing this on MacOS trying to switch language to French/Spanish etc. Apparently, I didn't switch language correctly as my java was still printing messages in English. And what was the sample output for this failed assertion in Japanese? I'm asking because I want to know if there were still any fragments in English, I could assert on.

Thanks. I reproduced this. It turned out that javac has localization in Japanese but not in European languages I tried.
