How to disable the "Optional used as field or parameter type" warning in IntelliJ? [duplicate]

Tags:

intellij-idea

Jetbrains has recently decided that java.util.Optional (as well as Guava's com.google.common.base.Optional) shouldn't be used as field or parameter type... thanks, but no thanks... How can this warning be disabled?

As a side note: triggering warnings on this specific usage of Optional seems completely unjustified...

How do you make a parameter optional in Java?

There are no optional parameters in Java. What you can do is overloading the functions and then passing default values.
