java - VerifyError 在 Java 8 中对 Lambda 表达式非法使用非虚函数调用

Question

我正在从事一个项目，该项目最近引入了 lambda 表达式。一个例子是这样的。

public class ExampleItemWriter implements ItemWriter<MyItem> {
    public void write(List<? extends MyItem> list) throws RepositoryException {
        list.stream().forEach((item)->{
            if (item == null) {
            }
        });
    }
}

我不认为 forEach() 中的细节与问题相关，但如果相关，我可以发布。整个代码中还有一些类似的其他表达式会抛出相同的异常。

我们有几个不同的环境运行相同的代码，只有其中一些抛出这个异常。我在这个问题上花了很多时间，最后把它贴在这里征求意见。这些环境看起来具有相同的 jdk 1.8.0_31，而我们使用的是 maven-compiler-plugin 3.2。

关于我们可以在哪里寻找的任何提示？我没主意了。谢谢，/w

原因可能是接口(interface)被一个在 java 8 上编译的版本所取代，其余代码在较低版本上，比如 java 5。为此 https://bugs.openjdk.java.net/browse/JDK-8004967 打开了 bug。

但是，我不认为这里是这种情况，因为您在 ExampleItemWriter 中使用 java8 功能并且必须在 java8 上编译它。所以不存在目标不一致的问题。你仍然可以考虑在 java8 上重建你的整个项目。
