尝试执行java.lang.ExceptionInInitializerError时，我有一个BufferedImage originalImage = ImageIO.read(in);。这只发生在生产VM上，而不是我的开发机器上。
我在生产VM上创建了一个带有上述行的小类，并成功编译并执行了它。然后我尝试按建议here添加java选项"-Djava.awt.headless=true -Dawt.toolkit=sun.awt.HToolkit"。没有帮助。然后我尝试按照建议here添加static {ImageIO.scanForPlugins();}。也没有帮助。我跑jHades试图查看罐子里是否有重叠的类。没有了。
现在我没有想法。 dev机器在Ubuntu 14.04上运行java 1.8.0_76-release-b198，生产VM在CentOS上运行java 1.8.0_60-b27。有什么指针吗？
