java - 尝试访问 Java 1.8 物理文件时检测到虚拟 Java 1.6

Question

我的机器安装了 Java 1.8 物理应用程序和 Java 1.6 虚拟应用程序。当启动与 JAva 1.8 相关的快捷方式时，它会获取 java 1.6 虚拟文件，但失败。

这是我在快捷方式失败时选择“详细信息”选项卡时观察到的代码

此外，当仅安装物理 1.8 时，应用程序运行正常，但当同一计算机上安装虚拟 1.6 时，应用程序会失败

<!--      the newest available version permitted by any of the version ranges.        -->
<!--      So, as of this writing, Webstart would download 1.7 update 25 at this step. -->
<!--      As later updates of 1.7 are released, Webstart will download those instead. -->
<!--      It will never download Java 1.8 since the version range does not permit it. -->

您的 AppV JRE 可能正在泄漏。当 AppData\LocalLow\Sun\Java\Deployment 中的 deployment.properties 文件在排序过程中未捕获并且 native JRE 开始从该文件读取时，可能会发生这种情况。引用http://packageology.com/2014/02/sequencing-java-the-definitive-guide-part-1/获取完整的测序指南。
