Question

最近我正在尝试调用通过Apache-CXF发布的REST服务。所有内容都嵌入在带有Jetty 9.4.1的Equinox 3.11.0中。

Container启动Jetty，为HTTP / 2配置：

[main] INFO org.eclipse.jetty.server.Server - jetty-9.4.1.v20170120
[main] INFO org.eclipse.jetty.server.handler.ContextHandler - Started o.e.j.s.ServletContextHandler@6f89f665{/,jar:file:///C:/workspaces/com.ebase.eox/cnf/generated/fw/org.eclipse.osgi/12/0/bundleFile!/,AVAILABLE}
[main] INFO org.eclipse.jetty.server.AbstractConnector - Started ServerConnector@187eb9a8{HTTP/1.1,[http/1.1, h2c]}{0.0.0.0:8080}
[main] INFO org.eclipse.jetty.util.ssl.SslContextFactory - x509=X509@1517f633(jetty,h=[],w=[]) for SslContextFactory@4fe01803(bundleentry://12.fwk1276261147/jettyhome/etc/keystore,bundleentry://12.fwk1276261147/jettyhome/etc/keystore)
[main] INFO org.eclipse.jetty.server.AbstractConnector - Started ServerConnector@3015db78{SSL,[ssl, alpn, h2, http/1.1]}{0.0.0.0:8443}

Wenn我通过https / ssl调用REST服务我收到错误：

似乎（我已经证明了）， PreEncodedHttpField 无法加载 ServiceLoader 上的所有HttpFieldPreEncoder实现。

    Iterator<HttpFieldPreEncoder> iter = ServiceLoader.load(HttpFieldPreEncoder.class,PreEncodedHttpField.class.getClassLoader()).iterator();

ServiceLoader只能看到 Http1FieldPreEncoder ，它与 PreEncodedHttpField 位于同一个Bundle中，因此可以观察到BundleClassLoader。此实现在索引“0”下注册。

在我的情况下，它应该使用HTTP / 2实现 HpackFieldPreEncoder ，它绑定在http2-hpack中，但 ServiceLoader

不可见

是否有任何解决方法可以使第二个实现对PreEncodedHttpField可见以避免我的异常？

谢谢
