java - 需要了解 JAVA 日志文件错误

Question

我正在运行一个名为 SIET 的 java 图像批处理实用程序在 Linux 下，它在初始加载图标后不运行。我的 Java 环境已全部设置完毕，如下所示。

java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) Server VM (build 23.25-b01, mixed mode)

随附日志文件以供进一步了解...

Answer 1

尝试执行:

System.setProperty("sun.awt.backingStore", "NotUseful");

看看它有什么作用？您知道什么是后备存储吗？
