JUnit tests started to fail after Apache Camel has been upgraded from 2.6.0 to 2.8.6

Question

We have upgraded our Camel version from 2.6.0 to 2.8.6 because of migration to JBoss 5 and all of our test have been failing since then. There is something about the namespace but I haven't found anything that could lead me to the right direction on the Apache Camel's website - on the contrary everything seems to be correct. Any ideas?

I think the camel spring support has been moved out of the core into camel-spring. Can you try to add this dependency?
