Description

With Camel 3.0.1, I am experiencing this error:

I am running Camel in Karaf OSGi environment with camel-groovy feature installed.  In old Camel 2.X, I had to install features camel-script, and camel-script-groovy, but they are no longer available.
 
Adding:

DynamicImport-Package:  groovy.*, org.codehaus.groovy.*

Fixes the issue.
