Listswith two identical methods
newArrayList(). No problem so far, but you should really pay attention which one to import. If you set up your project with Maven2 it's best practice to use the test scope on each test-specific dependency. That means wrongly importing
org.testng.v6.Listsin productive code would leed to some weird compiler errors on running the build scripts. So pay attention to import
com.google.common.collect.Listsinstead of the one from the TestNG API.
