Hi Felix,

I believe the exception is happening because you have the mysql-metadata-storage extension on your classpath and Tranquility apparently does not play well with it. Can you try removing it from your classpath and see if that works?

[Anthony Bobsin]

Hello,

Was there any update on this? I'm currently running into the same issue.

[David Lim]

Hey Anthony,

Are you getting the same exception stacktrace? Did you check to make sure Tranquility wasn't attempting to load the mysql extension?
