Fake implementation confuses development tools (IntelliJ)

[Christian Koop]

Hi, I'm adding support for your plugin to another one right now and saw that the JetBrains IntelliJ IDE automatically sees that your API method always returns null.

It achieves this by automatically generating an @Contract annotation for that (_ stands for any value. so no matter what you put in as first or second argument, it will always return null).

Would be nice if this could be improved.

Just ignore the messages for now, the actual API won't return null.
