Hi,

Please tell us more about the circumstances that lead to this issue. In which tool do you get this? What do you do to trigger this? Are you able to reproduce consistently? If yes, how?

Thanks,

Janos

Hi Janos

As you can see in the StackTrace I'm using the Gradle Scanner.
I only have seen this message once so far, I'm in the process of upgrading our SQ to 6.5.
I don't know yet whether I can reproduce the issue, it just happened to me right before I wrote the mail.

Regards
Björn
