在将jnlp从openjdk 8迁移到openjdk 9时，JarIndexAccess无法访问类jdk.internal.util.jar.JarIndex（在java.base模块中）

Question

我们有下面的jnlp

</jnlp>

在jnlp之上，可以与Oracle jdk 8正常工作。现在，我们迁移到openjdk 9，并使用icetea web在客户端打开jnlp文件。 添加了带有一些Java参数的j2se version =“ 9+”，但由于未找到sun / misc / JarIndex类而面临以下问题。 我知道该类已从openjdk 9中删除。 那么，我们需要使用任何替代方法还是有任何解决方法？

Answer 1

JarIndex在Java 9中移至内部包dk.internal.util.jar.JarIndex

-导入sun.misc.JarIndex;

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

由于JEP 260

如JEP 260所定义，sun.misc.JarIndex及其随附的InvalidJarIndexException不是“关键API”，因此应将它们从sun.misc中移出，并放入更合适的包装中以对其进行封装。
