Question

我已将以下代码重写为lambda表达式：

boolean updateAble = false;
for (Field field : fields) {
    if (field.isAnnotationPresent(Updateable.class)) {
        updateAble = true;
        break;
    }
}
if (udpateAble) {...}

我想把它重写为：

boolean updateAble = fields.stream().anyMatch(field -> field.isAnnotationPresent(Updateable.class));
if (udpateAble) {...}

此代码编译并且似乎已准备好部署，但抛出以下异常并且部署失败：

有什么方法可以解决这个问题吗？我知道使用lambdas并不是必需的，尽管有可能使用它们会很好。我已经使用Google搜索并搜索了stackoverflow，但我找不到解决方案。

在不同的论坛（包括这里 - 已经讨论了很多次 - 但很奇怪，我也找不到它）。你看到的ArrayIndexOutOfBoundsException确实是因为缺乏对带有glassfish的java-8的支持。你可以在这里尝试两件事 - 获得你可以获得的最新版本并祈祷它有效;只是注意到Oracle不支持这个服务器 - 他们确实有weblogic ......

或切换到paraya。
