Fixed issues:

* [JENKINS-40710](https://issues.jenkins-ci.org/browse/JENKINS-40710) - Match headers case-insensitively in `JnlpAgentEndpointResolver` in order to be compliant with HTTP2 lower-case headers.

    @Override
    public void postInitialize() throws Exception {
        Jenkins.getInstance().checkPermission(Jenkins.ADMINISTER);
    }
