> DefaultModelValidator.validateId is inefficient
> -----------------------------------------------
>
> Key: MNG-6629
> URL: https://issues.apache.org/jira/browse/MNG-6629
> Project: Maven
> Issue Type: Bug
> Components: core
> Affects Versions: 3.6.0
> Reporter: Stefan Oehme
> Priority: Major
>
>
> I'm currently optimizing a very large (2000+ submodule) project.
> DefaultModelValidator.validateId is one of the CPU hotspots, as it uses a
> regex for validating every ID in the model. Iterating over the characters and
> checking them against valid ranges would be faster and less memory intensive.
