["Elliotte Rusty Harold (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MNG-7714?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17695687#comment-17695687 ] 

Elliotte Rusty Harold commented on MNG-7714:
--------------------------------------------

I can reproduce this. Specifically,

       "final" <  "sp" // correct
       "final" <  "sp1" // correct
       "1.0.final-redhat-0001" < "1.0.sp-redhat-0001" // correct
        "1.0.final-redhat-0001" > "1.0.sp1-redhat-0001" // likely incorrect, investigating





> sp < final

> The claim is that sp < final, which if true is incorrect according to spec. 
> It is easy to demonstrate that this is not fixed and also not in line with the spec, with just this one important example (yes this does break for us):
> $ jbang org.apache.maven:maven-artifact:3.8.6 1.0.final-redhat-0001 1.0.sp1-redhat-0001
> Display parameters as parsed by Maven (in canonical form and as a list of tokens) and comparison result:
> 1. 1.0.final-redhat-0001 -> 1-redhat-1; tokens: [1, [redhat, [1]]]
>    1.0.final-redhat-0001 < 1.0.sp1-redhat-0001
> 2. 1.0.sp1-redhat-0001 -> 1.0.sp-1-redhat-1; tokens: [1, 0, sp, [1, [redhat, [1]]]]
> versus
> $ jbang org.apache.maven:maven-artifact:3.8.7 1.0.final-redhat-0001 1.0.sp1-redhat-0001
> Display parameters as parsed by Maven (in canonical form and as a list of tokens) and comparison result:
> 1. 1.0.final-redhat-0001 -> 1-redhat-1; tokens: [1, [redhat, [1]]]
>    1.0.final-redhat-0001 > 1.0.sp1-redhat-0001
> 2. 1.0.sp1-redhat-0001 -> 1-sp-1-redhat-1; tokens: [1, [sp, [1, [redhat, [1]]]]]
> As you can see, our `sp` release is now ordered after our `final` release despite this clear text in the "spec":
>     Non-numeric tokens ("qualifiers") have the alphabetical order, except for the following tokens which come first in this order: "alpha" < "beta" < "milestone" < "rc" = "cr" < "snapshot" < "" = "final" = "ga" < "sp"
> It's clear that this tokenization isn't really correct by any reasonable measurement, and breaking large amounts of (our) existing artifacts in the wild is definitely not OK.
