org.apache.derby.iapi.services.io.DerbyIOException
A subclass of IOException that carries a SQL state. The original reason for adding it was to separate between IOExceptions generated by the application stream and the ones generated by the Derby wrapper streams, see for instance RawToBinaryFormatStream. Without this distinction, the user would not be able to easily write catch-blocks to handle specific errors happening when reading streams.

                        "<stream-value>", // Don't show the whole value.
