Description

There is a NPE when using the imap mail component with quartz or the timer and pollEnrich as dicussed here:
http://camel.465427.n5.nabble.com/Schedule-file-mail-endpoint-td3356666.html#a3357538

I reproduced it on version 2.10.3 and 2.10.4 with
<route id="myTest">
<from uri="timer://foo?fixedRate=true&period=10000"/>
<pollEnrich uri="imap://userName@hostName?password=***"/>
<to uri="log:testroute?showAll=true&level=INFO"/>
</route>

We need to use it with the quartz component (so we can use a cron expression), but get the same error
<route id="myTest">
<from uri="quartz://testTimer?cron=0+?"/>
<pollEnrich uri="imap://userName@hostName?password=***"/>
<to uri="log:testroute?showAll=true&level=INFO"/>
</route>
