Slawomir Jaranowski commented on MSHARED-969:
---------------------------------------------
After my fix we have another feature, we can remove some variable from system
environment.
In method {{getEnvironmentVariables}} first is called {{addSystemEnvironment}}
which copied current system variable to local list, and when variable with the
same name exist it is not copied from system.
Next in {{getEnvironmentVariables}} we filter variables wich have {{null}}
value and in consequence we can filter system variables.
I added unit test to confirm this behavior.
