======================================================
Is the application using Maven?

System Environment Variables in Use
======================================================
What System.getEnv are they using?

File References / Reads / Writes that Need Directories Mapped
======================================================
new File(String)
new FileInputStream(String)
new FileOutputStream(String)
new FileOutputStream(String, boolean)

// Maybe Commons IOUtils as well?
