Description

Bug is still present with 2.19.0-SNAPSHOT, tested on 2017/02/02

Probably a race condition.

an xml containing this section:

  <bean id="jetty9" class="org.apache.camel.component.jetty9.JettyHttpComponent9">
    <property name="sslContextParameters" ref="mySslContext" />
  </bean> 

  <camelContext trace="true" id="camel" xmlns="http://camel.apache.org/schema/blueprint">
        <route>
            <!--from uri="jetty:https://localhost:8091/invoke?sslContextParametersRef=mySslContext&amp;matchOnUriPrefix=true"/-->
            <from uri="jetty9:https://localhost:8091/invoke?matchOnUriPrefix=true"/>
            <process ref="processor"/>
        </route>
    </camelContext>

generates this exception:
