Re: [google-cloud-sql-discuss] Re: Unusual error SQLNonTransientException: Internal error.

I don't know about the particular error mentioned there, but it looks like the user that generated that stack trace was using a very old, deprecated driver for connecting to Cloud SQL. We recommend using the standard, non-google driver if you are connecting from outside of google network, or the com.mysql.jdbc.GoogleDriver driver if you are connecting from App Engine. Specifically you should follow the appropriate connection instructions from the "connecting to instances" set of pages on our docs at https://cloud.google.com/sql/docs/.
