产生原因是在做jfreechart demo的时候.修改图表标题为中文的时候,点解确定.或者没修改点击退出.程序直接退出

 

例子代码

    }

        final BarChart3DDemo1 demo = new BarChart3DDemo1("3D Bar Chart Demo 1");
        RefineryUtilities.centerFrameOnScreen(demo);
        demo.pack();
        demo.setVisible(true);
    }
}

 

jfreechart是1.0.13

依赖的jar包

 

产生bug截图.貌似je上传的文件下载不了...图片显示不了..

 

btw:这是jfreechart的bug还是java的bug呢?控制台输出的让我去sun的主页报告..
