通过 WebStart 运行时 Java 7 更新 55 JacORB 错误

问题描述

自从更新到 Java 7 update 55 后，我无法运行我的 WebStart java 应用程序.

Since updating to Java 7 update 55, I'm not able to run my WebStart java application.

当通过 WebStart 启动时，此应用程序在 Java 7 update 51 下运行良好.

This application worked fine under Java 7 update 51 when launched via WebStart.

在 WebStart 之外启动时，它也适用于更新 55.

It also works with update 55 when launched outside of WebStart.

对于进一步的调查点有什么建议吗?

Any suggestions for further investigation points?

看起来这个问题已经在这里修复:

Looks like this issue has been fixed here:

https://bugs.openjdk.java.net/browse/JDK-8042789

这有望在 7 月 15 日包含在下一个 CPU 中

This will hopefully be included in the next CPU on July 15th

看起来导致此问题的更改已恢复，因此它现在再次使用当前线程类加载器.

Looks like the change that caused this issue was reverted so it now uses the current thread classloader again.
