-----------------------------------------

             Summary: ConflictResolver STANDARD verbosity misbehaves
                 Key: MRESOLVER-357
                 URL: https://issues.apache.org/jira/browse/MRESOLVER-357
             Project: Maven Resolver
          Issue Type: Bug
          Components: Resolver
    Affects Versions: 1.9.9, 1.9.8
            Reporter: Tamas Cservenak
             Fix For: 1.9.10


As per use report, the 1.9.8 and 1.9.9 versions produce different "verbose tree" that previous versions:
{noformat}
Input node:
some-group:a:jar:1.0 [compile]
+- some-group:b:jar:1.0 [compile]
|  +- some-group:c:jar:1.0 [compile]
|  +- some-group:c:jar:2.0 [compile]
|  \- some-group:d:jar:1.0 [compile]
+- some-group:c:jar:2.0 [compile]
+- some-group:c:jar:1.0 [compile]
\- some-group:d:jar:2.0 [compile]

Transformed node:
some-group:a:jar:1.0 [compile]
+- some-group:b:jar:1.0 [compile]
|  \- some-group:c:jar:2.0 [compile] (nearer exists)
+- some-group:c:jar:2.0 [compile]
\- some-group:d:jar:2.0 [compile] {noformat}
The d:1.0 should not be removed.

Seems that code comment "leaving only 1 loser" is present in comments only, but the actual code does not deliver this promise (the check is wrong, it should check for same GAs and not ANY child count).
