Examples with NegotiatingServerConnectionFactory org.eclipse.jetty.server.NegotiatingServerConnectionFactory used on opensource projects

Example 1 with NegotiatingServerConnectionFactory

use of org.eclipse.jetty.server.NegotiatingServerConnectionFactory in project dropwizard by dropwizard.

the class Http2ConnectorFactory method build.
