Slawomir Jaranowski commented on MSHARED-969:
---------------------------------------------

In fixed code system environment is not set yet - it happens later.
https://github.com/apache/maven-shared-utils/blob/360fd973130d4e80bbb0df2e6b30b7a54ec5f324/src/main/java/org/apache/maven/shared/utils/cli/Commandline.java#L408-L425
by call:
{code}
        String[] environment = getEnvironmentVariables();
...
        process = Runtime.getRuntime().exec( getShellCommandline(), environment 
);
{code}

I fixed method {{getEnvironmentVariables()}}

In original code we never have null as environment value
{{code}}
            environmentVars[i] = name + "=" + value;
{{code}}

if {{value}} was null - it was replaced by {{"null"}} string.
