    Checks if the connection has not been closed and is still valid. The validity is checked by checking that the connection is not closed.
    
    Specified by:
    
    isValid in interface java.sql.Connection
    
    Parameters:
    timeout - This should be the time in seconds to wait for the database operation used to validate the connection to complete (according to the JDBC4 JavaDoc). This is currently not supported/used.
    
    Returns:
    true if the connection is valid, false otherwise
    
    Throws:
    
    java.sql.SQLException - if the parameter value is illegal or if a database error has occurred

    setClientInfo will throw a SQLClientInfoException unless the properties parameter is empty, since Derby does not support any properties. All the property keys in the properties parameter are added to failedProperties of the exception thrown, with REASON_UNKNOWN_PROPERTY as the value.
    
    Specified by:
    
    setClientInfo in interface java.sql.Connection
    
    Parameters:
