java - HTTP/2 和 jetty : Max local stream count 100 exceeded

Question

在使用基本的 HTTP/2 GET 请求时，Jetty 似乎没有重用其内部流。大约 100 个请求后，它抛出以下异常:

Caused by: java.lang.IllegalStateException: Max local stream count 100 exceeded

我使用的代码如下:

HTTP2Client http2Client = new HTTP2Client();
http2Client.start();

HttpClient client = new HttpClient(new HttpClientTransportOverHTTP2(http2Client), ssl);
        client.start();

for (int i = 0; i < 1000; i++) {
    System.out.println(i);
    ContentResponse response = client.GET("https://http2.akamai.com");
    System.out.println("response code: " + response.getStatus());
}

我进一步研究了 Jetty 的源代码，它为每个请求创建一个新的流。为什么会这样？

我有什么遗漏的吗？这使得它几乎无法用于 API 请求等。

您遇到了一个已修复的错误。

请更新到 Jetty 9.3.7.RC0 或更高版本。

谢谢!
