功能运算符导致JPA崩溃？（虫子？）

我在JPA和Java8函数编程方面遇到了一个非常奇怪的问题

我有一个

学生

和

演示

班，他们的关系是双向的。在Java7中一切都很好，但我只是切换到Java8

此有效（可见是私有的，没有设置程序）：

此崩溃：

public static void setAllVisible(boolean visible) {
    new PresentationRepository().findAll().forEach(x -> x.visible = visible);        
    //same for new PresentationRepository().findAll().stream().forEach(x -> x.visible = visible);
}

多次出现此异常：

这是什么原因造成的？也许还值得一提的是，我偶尔会遇到编译崩溃，他们要求我将项目发送给Oracle。

你会发现当前的EclipseLink不支持Java 1.8语法；看看

我将DataNucleus v4.0用于我的项目，并适用于Java 1.8
