> 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:
> !visualvm.PNG!
> The number of {{parseVersion}} calls seems excessive.
> See attached {{visualvm_settings.xml}} for reference.
