[jira] Created: (MNG-4685) When executing mvn --version, Maven displays Java version incorrectly

When executing mvn --version, Maven displays Java version incorrectly
---------------------------------------------------------------------

                 Key: MNG-4685
                 URL: http://jira.codehaus.org/browse/MNG-4685
             Project: Maven 2 & 3
          Issue Type: Bug
    Affects Versions: 2.2.1
         Environment: Microsoft Windows XP, Home Edition, vesrion 2002, Service Pack 3; Java 1.6.0_20 (has been updated automatically).
            Reporter: Oleksij Lupandin
            Priority: Minor


I suppose, Maven detects Java version upon the folder name of Java home, and it is not always correct.
My Java home is "C:\Program Files\Java\jdk1.6.0_15". My Java developer kit is updated automatically. Its version is 1.6.0_20 now. When I run command "java -version", I get the following output:

-----
D:\>java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing)
-----

When I run the command "mvn --version", I expect output like

-----
D:\>mvn --version
Apache Maven <some values...>
Java version: 1.6.0_20
Java home: C:\Program Files\Java\jdk1.6.0_15\jre
<other output...>
-----

Instead, the output is as follows:

-----
D:\>mvn --version
Apache Maven 2.2.1 (r801777; 2009-08-06 22:16:01+0300)
Java version: 1.6.0_15
Java home: C:\Program Files\Java\jdk1.6.0_15\jre
Default locale: uk_UA, platform encoding: Cp1251
OS name: "windows xp" version: "5.1" arch: "x86" Family: "windows"
-----

So, the procedure of how Maven defines Java version must be corrected.

bq. My Java home is "C:\Program Files\Java\jdk1.6.0_15"
And this is what Maven by design uses. If you want to use a different installation, please update your JAVA_HOME environment variable accordingly.
