Affected Version: 1.2 for IDEA 2019.x
OS: Windows
IDE: IDEA Ultimate 2019.2

It should underline extends and recommend changing it to implements rather than throwing an exception.

This is a bug in the plugin. IntelliJ IDEA is complaining because the plugin wants to mark an error in a different file than is being inspected.
