fix(jdbc): be resilient to DataException

We usually fail fast, but when a DataException is thrown it means the JDBC driver throws an exception with error code 22: data exception.
As the exception is from the data not the database or the network, there is no point of failfast, we throw a QueueException that may or may not be handled gracefully by the call site.
