Let me try a shot in the dark. As far as I remember the Hudson JDK does
not have JAI installed in the JDK. And the above code might need it.

The practice so far in GeoTools has been to declare a "provided" 
dependency to JAI in all modules that do need it. Maybe process needs
it too.

 From the coverage pom.xml:

<dependency>
       <groupId>javax.media</groupId>
       <artifactId>jai_imageio</artifactId>
       <!-- The version number is specified in the parent POM. -->
       <scope>provided</scope>  <!-- Users should execute JAI installer. -->
     </dependency>

Now, I personally disagree on this vision and think we should include
the jai jars as normal dependency, but this is another discussion.

Cheers
Andrea
