ASF GitHub Bot commented on MNG-6255:
-------------------------------------

Github user Tunaki commented on the issue:

    Looks like we have a similar bug in `mvn.cmd`. The added `testJvmConfigFileCR` test fails
on Windows:
    
    ```
    testJvmConfigFileCR(org.apache.maven.it.MavenITmng6255FixConcatLines)  Time elapsed: 1.983
sec  <<< FAILURE!
    junit.framework.ComparisonFailure: null expected:<ok[]> but was:<ok[-Xms256m-Xmx512m]>
      at junit.framework.Assert.assertEquals(Assert.java:81)
      at junit.framework.Assert.assertEquals(Assert.java:87)
      at org.apache.maven.it.MavenITmng6255FixConcatLines.runWithLineEndings(MavenITmng6255FixConcatLines.java:89)
      at org.apache.maven.it.MavenITmng6255FixConcatLines.testJvmConfigFileCR(MavenITmng6255FixConcatLines.java:50)
    ```
    
    Looks like the carriage returns at the end of the line were stripped and everything was
put on a single line.

>             Project: Maven
>          Issue Type: Bug
>          Components: Command Line
>    Affects Versions: 3.5.0
>         Environment: Windows 7 with MINGW64 environment via Git for Windows 0.1.1 including

> A project with a {{.mvn/jvm.config}} file that has *CRLF* line endings will not parse
it correctly. The script uses the {{tr}} command to change *LF* to space, but this leaves
*CR* behind. For example, with the {{jvm.config}} file containing the text {{-Xmx1024m -Xms512m}}
followed by *CRLF*, the following error message is printed:
> {code}
> $ mvn install
> Error: Could not create the Java Virtual Machine.
> Error: A fatal exception has occurred. Program will exit.
> Invalid initial heap size: -Xms512m
> {code}
