   I am experiencing the same issue, even though locale is en_US and am unable to build the project.

   Error message:

   Failed tests:   testToString(com.microsoft.java.debug.core.adapter.formatter.NumericFormatterTest): NumericFormatter should be able to format double correctly. expected:<111[.]000000> but was:<111[,]000000>
   

   Locale:

   $ env | grep LC
   LC_CTYPE=UTF-8
   LC_ALL=en_US.UTF-8
   

   Java Version:

   $ java --version

   This affects me too. The test should not assume that the separator for double is '.'

   OS:
   Ubuntu 20.04

   Locale:
   env | grep LC
   LC_ADDRESS=de_DE.UTF-8
   LC_NAME=de_DE.UTF-8
   LC_MONETARY=de_DE.UTF-8
   LC_PAPER=de_DE.UTF-8
   LC_IDENTIFICATION=de_DE.UTF-8
   LC_TELEPHONE=de_DE.UTF-8
   LC_MEASUREMENT=de_DE.UTF-8
   LC_TIME=de_DE.UTF-8
   LC_NUMERIC=de_DE.UTF-8

   Hi zupatisc, I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

   Suggestions

   • Enforce a consistent locale when formatting numbers:

     • In your test or setup code, call:

       Locale.setDefault(Locale.US);

     • In Maven Surefire, add to your pom.xml:

       <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-surefire-plugin</artifactId>
         <configuration>
           <systemPropertyVariables>
             <user.language>en</user.language>
             <user.country>US</user.country>
           </systemPropertyVariables>
         </configuration>
       </plugin>

       (See: https://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html)
     • Or run tests via:

       mvn test -Duser.language=en -Duser.country=US

   • Update your formatter to use a locale-specific API, e.g.:

     String result = String.format(Locale.US, "%.6f", 111.0);
