/**
 * Extract location information for Informix DB.

 * <p>
 * For Informix the location information is not present in the exception
 * itself. It has to be extracted from the connection.</p>
 *
 * <p>
 * In this case the connection is accessed via reflection to call the
 * corresponding method.</p>
 *
 * <p>
 * In case connection gets wrapped later it needs to be unwrapped here.</p>
