* because it simply returns the SystemEnvironment object that System.getenv() gives us. The
* relevant portion in the source code is marked as "// android changed", so presumably it's not
* the case in the original version of the Apache Harmony project.
* <p>
* Note that simply passing the environment variables we want to Process.exec won't be good
* enough, since that would override the environment we inherited completely.
* <p>
* We needed to be able to set a CLASSPATH environment variable for our new process in order to
* use the "app_process" command directly. Note: "app_process" takes arguments passed on to the
* Dalvik VM as well; this might be an alternative way to set the class path.
