                                             throws java.io.IOException

public static java.util.Properties getSystemEnvVars(boolean caseSensitive)
                                             throws java.io.IOException
```
    Return the shell environment variables. If caseSensitive == true, then envar keys will all be upper-case.
    
    Parameters:
    
    caseSensitive - Whether environment variable keys should be treated case-sensitively.
    
    Returns:
    
    Properties object of (possibly modified) envar keys mapped to their values.
    
    Throws:
    
    java.io.IOException - in case of an error.
  - setEnvVarSource
```
public static void setEnvVarSource(OperatingSystemUtils.EnvVarSource source)
```
    Set the source object to load the environment variables from. Default implementation should suffice. This is mostly for testing.
    
    Parameters:
    
    source - the EnvVarSource instance that loads the environment variables.
