----------------------------------
Resolution: Not A Bug
Assignee: Benjamin Bentmann
This is a consequence of [the way conflict resolution
works|http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html].
The relevant bits from the project's dirty dependency tree:
{noformat}
ripe:web:war:0.0.1-SNAPSHOT
org.hibernate:hibernate-entitymanager:jar:3.4.0.GA:test
dom4j:dom4j:jar:1.6.1:compile
xml-apis:xml-apis:jar:1.0.b2:compile
org.axonframework:axon-core:jar:0.7.1:compile
dom4j:dom4j:jar:1.6.1:compile
{noformat}
Note that there are two paths leading to {{dom4j}}, one having a dependency on
{{xml-apis}} and one not. As both {{dom4j}} dependencies occur on the same
graph depth, the one seen first gets picked, including its transitive
dependencies.
