我们有下面的jnlp

以上 jnlp 在 oracle jdk 8 上正常工作。现在我们正在迁移到 openjdk 9 并使用 icetea web 在客户端打开 jnlp 文件。添加了带有一些 java-args 的 j2se version="9+"，但由于找不到 sun/misc/JarIndex 类而面临以下问题。我知道这个类已从 openjdk 9 中删除。那么我们是否需要使用任何替代方法或者我们是否有任何解决方法？

JarIndex在 Java 9 中被移动到内部包dk.internal.util.jar.JarIndex

-导入 sun.misc.JarIndex；

+import jdk.internal.util.jar.JarIndex；

由于JEP 260

sun.misc.JarIndex 及其附带的 InvalidJarIndexException 不是 JEP 260 定义的“关键 API”，因此应将它们从 sun.misc 中移出并放入可以封装的更合适的包中。
