Yes Camel is included in Fuse ESB and Fuse ESB Enterprise.
The latter is using a newer version of Camel, eg 2.10, where as Fuse ESB is using 2.9.
The etc/jre.properties file is not from Camel, but in fact from the Karaf container. And likewise Fuse ESB uses Karaf 2.2.x, and Fuse ESB Enterprise is using Karaf 2.3.x.
In your case you can change the imports in jre.properties to get this working in your system. But bear in mind such as change is a global change, and can cause side effects for other parts. You can do this change in the Fuse ESB Enterprise product as well.
