in Jetty Configuration Options for SSL

explains if ValidateCertificates is true then 

Modify em-jetty-config.xml and enable appropriate validation methods. This modification means that either both or the appropriate one of these following settings have to be enabled:

<Set name="enableCRLDP">true</Set> - the validation uses Certificate Revocation List file URL that is specified as an extension of X.509 certificate.

<Set name="enableOCSP">true</Set> - the validation uses OCSP responder. This OCSP responder URL can also be specified in X.509 certificate as an extension. If the certificate does not define this OCSP responder URL, it can be specified with <Set name="ocspResponderURL">http://example.com/ocsp</Set>.
