IntelliJ throws an exception about Dagger plugin

[adhulipa]

I'm running into a non-user-experience-breaking list of exceptions with the dagger plugin.
It should be noted that I was able to see the little "🗡" icons (and also the different orientation variations of it) in the gutter and was able to navigate to the beans.

However, I believe this error message may be useful to the project.
