I noticed that DependencyConvergence can take up to 10 seconds or even more in
modules with almost 300 direct and transitive dependencies (reported by
{{dependency:tree}}).
These modules are part of a JEE project based on JBoss EAP 6.4 which imports a
couple of EAP BOMs. Unfortunately I am not allowed to share this project.
I profiled the rule via VisualVM and these are the top 5 hotspots:

The number of {{parseVersion}} calls seems excessive.
See attached {{visualvm_settings.xml}} for reference.
