When using the xmlunit-assertj module in an OSGI environment tests fail because of the use of classes in the org.assert.core.internal package. This package is not marked as exposed and can therefor not be accessed.

The only use for this import seems to be the Failures class. So far I haven't found a way to avoid it so I'm also creating an issue with the assertj-core module to request it to be moved to the util package.
