> Key: MNG-4918
> URL: http://jira.codehaus.org/browse/MNG-4918
> Project: Maven 2 & 3
> Issue Type: Bug
> Affects Versions: 3.0, 3.0.1
> Environment: all
> Reporter: Sebastian Annies
> Attachments: fix.patch, test.patch
>
>
> The error occured in our Project with more than 60 submodules and aggregating
> JavaDoc. Due to the forking of the LifeCycle many clones of the MavenProject
> object seem to be performed. Since MavenProject#clone doubles the entries in
> the list of active profiles we start with one active profile and after a few
> dozen clones the list of active profiles exceeds 10.000.000 elements. This
> will than kill the VM by OOME.
> mavenProject.getActiveProfiles().size() == 1
> mavenProject.clone().getActiveProfiles().size() == 2
> mavenProject.clone().clone().getActiveProfiles().size() == 4
> and so on
