android studio attaching,Attaching Kotlin sources to AAR doesn't work in Android Studio

I am trying to add Kotlin sources of an AAR in Android Studio 3.3.2. It doesn't work when I select "Choose Sources..." and choose the corresponding source.jar. Android Studio only displays "Attaching..." but nothing happens, as seen in the screenshot below.

Either there is a Bug in Android Studio since I can see a NoSuchElementException in the logs or the source.jar is not as needed. Any hint's to solve the issue are welcome.

Here is the exception:

java.util.NoSuchElementException
