java - Parallel Stream.forEach 抛出的异常

Question

当 Consumer 抛出异常时，我用 Google 搜索了从并行 Stream 的 forEach 方法抛出的内容，但没有没有找到任何关于它的信息。它会抛出类似于 C# 的 AggregateException 或其他东西的东西吗？

Answer 1

根据 http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ForkJoinTask.html#fork() 将异常转发给调用者

Rethrown exceptions behave in the same way as regular exceptions, but, when possible, contain stack traces (as displayed for example using ex.printStackTrace()) of both the thread that initiated the computation as well as the thread actually encountering the exception; minimally only the latter.
