Maybe this one needs reopening?

java -jar ~/.m2/repository/org/apache/maven/maven-artifact/3.5.4/maven-artifact-3.5.4.jar "2.9" "2.9-1" "2.9.0.rc-1" "2.9"
Display parameters as parsed by Maven (in canonical form) and comparison result:
1. 2.9 == 2.9

> if ComparableVersion A > B and B > C, then it's required that A > C. In the attached test patch, I'm demonstrating a case where it's failing. Please note that the situation is not that rare, please see issues https://netbeans.org/bugzilla/show_bug.cgi?id=226100 and https://netbeans.org/bugzilla/show_bug.cgi?id=240845 at netbeans.org and https://jira.codehaus.org/browse/MPIR-247
