    7Clone fragment #1 returns variable that with type org.jfree.chart.entity.ChartEntity , while Clone fragment #2 returns variable that with type org.jfree.chart.renderer.xy.XYDotRenderer
    8Not all possible execution flows end in a return statement
    9The refactoring of the clones is infeasible, because classes org.jfree.chart.entity.ChartEntity and org.jfree.chart.renderer.xy.XYDotRenderer do not have a common superclass
