The spec in package javadoc is to serve as "ultimate ref" (as other pages on
Maven Site may get outdated).

[~dmlloyd] please review and comment, also will add to package-info the spec
(adapting your text) to serve as "ultimate ref" (as other pages on Maven Site

> Unexpected handling of qualifiers in GenericVersionScheme
> ---------------------------------------------------------
>
> Key: MRESOLVER-336
> URL: https://issues.apache.org/jira/browse/MRESOLVER-336
> Project: Maven Resolver
> Issue Type: Bug
> Components: Resolver
> Affects Versions: 1.9.5
> Reporter: David M. Lloyd
> Assignee: Tamas Cservenak
> Priority: Major
>
> Given the following:
> {code}
> $ jbang --main=org.eclipse.aether.util.version.GenericVersionScheme
> org.apache.maven.resolver:maven-resolver-util:1.9.5 0.0.0.ga.ga.foo foo
> Display parameters as parsed by Maven Resolver (in canonical form and as a
> list of tokens) and comparison result:
> 1. 0.0.0.ga.ga.foo -> 0.0.0.ga.ga.foo; tokens: [0, 0, 0, foo]
> 0.0.0.ga.ga.foo == foo
> 2. foo -> foo; tokens: [foo]
> {code}
> This is expected iff zero-prefixed qualifiers are considered equal to the
> bare qualifier, which does seem to be the case *mostly*. However, we also
> have this:
> {code}
> $ jbang --main=org.eclipse.aether.util.version.GenericVersionScheme
> org.apache.maven.resolver:maven-resolver-util:1.9.5 ga.ga.foo foo
> Display parameters as parsed by Maven Resolver (in canonical form and as a
> list of tokens) and comparison result:
> 1. ga.ga.foo -> ga.ga.foo; tokens: [0, 0, foo]
> ga.ga.foo < foo
> 2. foo -> foo; tokens: [foo]
> {code}
> In this case we have "zero"-valued qualifiers but no leading numerical
> segment, which unexpectedly changes the parsing rules. I would expect
> {{ga.ga.foo == foo}} as above. Is this a bug? Is there an explanation for
> this behavior? The spec doesn't seem to directly address this.
