how to fix it.
error throw at this line, but the line has nothing todo with Priority.
public class Log4JLogger implements Log, Serializable {
/** Serializable version identifier. */
private static final long serialVersionUID = 5160705895411730424L;
// ------------------------------------------------------------- Attributes
/** The fully qualified name of the Log4JLogger class. */
private static final String FQCN = Log4JLogger.class.getName(); ////<<<--this line error
private transient volatile Logger logger = null;
/** Logger name */
private final String name;
private static final Priority traceLevel; // this line's has "org.apache.log4j.Priority"
