当我使用Java 8特定代码时,Jetty无法使用ArrayIndexOutOfBoundsException加载

Question

我在嵌入式Jetty Web服务器中使用Jersey.除了一个非常具体的案例外,一切都运作良好.我有一个用户列表,当客户端到POST/ user时,我想将用户添加到列表中.没问题,除非我想检查现有用户删除具有相同用户名的任何用户(以便更新用户).

@POST
public void createUser(User user) {
    // The first line causes the failure:
    InventoryServer.getUsers().removeIf(e -> e.getUsername().equals(user.getUsername()));
    InventoryServer.getUsers().add(user);
    InventoryServer.save();
}

奇怪的是,当这条线存在时,Jetty甚至不会启动.它给了我一个ArrayOutOfBoundsException.我在异常时调试了程序,似乎它发生在方法中SignatureParser.current().网上有几个人提到,当你使用名为asm的库运行Java 8字节代码时会发生这种情况,当然,我发现它是jetty-server的依赖.我无法更新它,因为最新版本的Jetty需要旧版本的asm.

我想解决方案就是不使用任何Java 8特有的功能,但这似乎是一个非常不完整的解决方案.有没有办法解决这个问题并继续使用Java 8？

这是堆栈跟踪:

您需要拥有至少9.2.0的Jetty版本并升级到Jersey 2.22.1以获得Java 8功能支持.
