Robert Varga commented on MRESOLVER-42:
---------------------------------------
Fix at [https://github.com/apache/maven-resolver/pull/16,] should be backported
to 1.0.x.
> DefaultArtifact(String) is inefficient
> --------------------------------------
>
> Key: MRESOLVER-42
> URL: https://issues.apache.org/jira/browse/MRESOLVER-42
> Project: Maven Resolver
> Issue Type: Improvement
> Components: resolver
> Affects Versions: Maven Artifact Resolver 1.0.3, Maven Artifact Resolver
> 1.1.0
> Reporter: Robert Varga
> Priority: Major
>
> DefaultArtifact(String) always compiles the coordinate matching pattern. This
> leads to sub-optimal performance when this constructor is used.
> The pattern being matched should be a constant, so that we instantiate only a
> matcher, which is fast compared to Pattern.compile(String).
