When I run integration tests with arquillian-jacoco I get IllegalClassFormatException.

It turned out that jacoco conflicts with jrebel, so don't use arquillian-jrebel or pure jrebel together with jacoco. If you have previously deployed your tests with jrebel, you should undeploy them and restart the server.

Very specific to jrebel-extension - shall we spend time investigating it?
