java - Java 向后兼容性

Question

我有一个 Fedora 29 i386 虚拟机，安装了两个版本的 java：

java-11-openjdk.i386 (/usr/lib/jvm/java-11-openjdk-11.0.ea.28-2.fc29.i386/bin/java)

java-1.8.0-openjdk.i386 (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.201.b09-6.fc29.i386/jre/bin/java)

当我使用 openjdk 8 运行我的 java swing 应用程序时，应用程序运行良好，而使用 openjdk 11 时会引发异常：

Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't load library: /usr/lib/jvm/java-11-openjdk-11.0.ea.28-2.fc29.i386/lib/libawt_xawt.so

在新版本的java中有没有向后兼容？
