Question

我有一个连接到Web服务的webstart应用程序。清单有：

Permissions: all-permissions

jnlp有：

<security>
  <all-permissions/>
</security>

但是，当创建与Web服务的连接时，我得到java.lang.SecurityException: setContextClassLoader（下面的完整堆栈跟踪）。当我直接运行应用程序（没有webstart）时，它工作正常。在我的设置中有什么我应该检查或更改以解决问题吗？

注意：我正在使用Java 8.应用程序在构建121时工作正常，但在构建123,124或125（最新版本）时失败。所以要么我的设置很好，并且在b121和b123之间引入了一个错误，或者在b123中修复了一个错误，这在我的设置中暴露了一个问题。

Answer 1

我应该更仔细地阅读堆栈跟踪。 java.util.concurrent.ForkJoinWorkerThread$InnocuousForkJoinWorkerThread.setContextClassLoader抛出异常，这是一个默认的，无权限的工作线程。已在this post之后进行了更改，这是diff。

我正在访问网络服务：

CompletableFuture.runAsync(accessWebservice());

使用默认的ForkJoinPool线程池，它本身依赖于新的InnocuousForkJoinWorkerThread，如果调用setContextClassLoader则抛出异常。

解决方法：

CompletableFuture.runAsync(accessWebservice(), executor); //provide an executor

Webstart应用程序：SecurityException：setContextClassLoader
