Some Guava features were really useful for Java 7 application because Guava was bringing APIs missing in the JDK. Java 8 fixed some of these limitations. When migrating an application to Java 8 or even when starting a new one, it's recommended to prefer Java 8 APIs over Guava ones to ease its maintenance: developers don't need to learn how to use two APIs and can stick to the standard one.

This rule raises an issue when the following Guava APIs are used:
