Daml 在快速入门教程中启动沙盒和导航器时出现问题

我正在处理这个问题。启动沙盒时，我收到一些警告消息：

WARNING: An illegal reflective access operation has occurred 
WARNING: Illegal reflective access by com.google.protobuf.UnsafeUtil (file:/home/vantage/.da/packages/sandbox/6.0.0/lib/protobuf-java-3.5.1.jar) to field java.nio.Buffer.address
WARNING: Please consider reporting this to the maintainers of com.google.protobuf.UnsafeUtil
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

当我启动Navigator时也是如此：

Version 1.1.1
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.google.protobuf.UnsafeUtil (file:/home/vantage/.da/packages/navigator/1.1.1/navigator-1.1.1.jar) to field java.nio.Buffer.address
WARNING: Please consider reporting this to the maintainers of com.google.protobuf.UnsafeUtil
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

我是否应该担心某个地方出了问题？

此警告是因为gRPC使用了一些操作，这些操作在Java 8以上已被弃用。我假设您正在使用一个相当新的JRE，这就是为什么您会看到这个错误

他们大约在一个月前解决了这个问题，直到更改向上传播到更高级别的库中需要时间，所以它可以包含在沙盒和导航器中

见：

TL；DR：暂时忽略警告，它是无害的，会得到修复。：）
