StackOverflowError in Slick ExpandSums

[Daniel Skogquist Åborg]

Hi,

I've got a curious exception in production mode of my app, which I'm finding difficult to reproduce or error hunt:

[error] a.a.ActorSystemImpl - Uncaught fatal error from thread [application-akka.actor.default-dispatcher-10] shutting down ActorSystem [application]

java.lang.StackOverflowError: null

Anyone know what this error might mean? Unfortunately the stack trace does not indicate where in my code this is going wrong, and it only happens in the production mode, so it's difficult to find the source of it. Any better way to error debug these kind of messages?

Thanks,

Daniel

Is there any way to find out where in my code this error originates from? It doesn't seem to be in the stack trace Slick produces.

Found the problem; some data in my database had invalid character encodings in a UTF-8 VARCHAR, which appears to have tripped up Slick somehow.
