进行POST时java.net.HttpClient失败并出现EOFException

Question

我有一个使用openjdk-11.0.1 java.net.HttpClient向REST（ish）端点发出多部分POST请求的应用程序。该端点在执行任何工作时都会阻塞响应，当工作完成时，它将返回响应。此端点的性质是，响应可以在1s到1d的范围内进行，因此该连接可以保持非常很长时间。

因此，无论如何，即使目标服务器上的进程似乎仍然可以正常执行，最近我也开始遇到以下错误。是否有人对导致此错误的可能原因有任何想法？

这是我的HttpClient的创建：

default HttpClient create() {
    final SSLContextBuilder sslContextBuilder;

    try {
        sslContextBuilder = new SSLContextBuilder().loadTrustMaterial(TrustSelfSignedStrategy.INSTANCE);

    }

    // PREVENTS HOST VALIDATION
    final Properties props = System.getProperties();
    props.setProperty("jdk.internal.httpclient.disableHostnameVerification", Boolean.TRUE.toString());

    // SHOULD PREVENT HOST VALIDATION
    final SSLParameters sslParams = new SSLParameters();
    sslParams.setEndpointIdentificationAlgorithm(null);

    try {
        final SSLContext sslContext = sslContextBuilder.build();
        ignoreExpiredCerts(sslContext);

        return HttpClient.newBuilder().version(Version.HTTP_1_1).sslContext(sslContext).sslParameters(sslParams)
            .build();
    } catch (KeyManagementException | NoSuchAlgorithmException e) {
        throw new RuntimeException("Unable to build HttpClient", e);
    }
}

private void ignoreExpiredCerts(final SSLContext sslContext) throws KeyManagementException {

    }

    try {

        }

        } catch (final CertificateExpiredException e) {
            if (!logged.get()) {
            LOGGER.warn("Server certificate expired", e);
            logged.set(true);
            }
        } catch (final Exception e) {
            if (e.getCause() != null && e.getCause().getCause() != null
