Precondition Violations (3)
Row |
Violation |
1 | Type org.jfree.chart.renderer.xy.XYSplineRenderer.ControlPoint does not match with type org.jfree.data.statistics.DefaultStatisticalCategoryDataset |
2 | Not all possible execution flows end in a return statement |
3 | The refactoring of the clones is infeasible, because classes org.jfree.chart.renderer.xy.XYSplineRenderer.ControlPoint and org.jfree.data.statistics.DefaultStatisticalCategoryDataset do not have a common superclass |
