    @tillrohrmann That's all right. I know you are very busy. Just a little question, I have
reviewed PR(#6202). I saw it used `Exception`, and there is a suggestion from Stephan in May
7 : 
    
    ```
    I would use Throwable in the signatures. It may always be that some Error is the cause
(class not found, etc.)
    ```
    
    So I replaced the `Exception ` to `Throwable` in this PR, do you think it can be consider?
If not, I would close this PR.
