There are some existing integration tests that ensure that these constants match the constants defined in the fcrepo4 codebase. Could a similar test be added for this?

For completeness, it would also be good to add this to the unit test here: https://github.com/fcrepo4/fcrepo-camel/blob/master/src/test/java/org/fcrepo/camel/FcrepoConstantsTest.java

I suspect these Travis failures will go away once the fcrepo PR has been merged (pending response to code review comments).
