    1Type org.jfree.chart.axis.QuarterDateFormat does not match with type org.jfree.data.KeyedObject
    2Not all possible execution flows end in a return statement
    3The refactoring of the clones is infeasible, because classes org.jfree.chart.axis.QuarterDateFormat and org.jfree.data.KeyedObject do not have a common superclass
