> OutOfMemoryError when using profiles and pom inheritance

> Key: MNG-2813

> Project: Maven 2
> Issue Type: Bug
> Components: Profiles
> Affects Versions: 2.0.4

>
> When using profiles and POM inheritance, Maven grows out of heap space. This
> especially happens when using Xpp3Dom's combine.children="append" on plugin
> configurations in the POMs.
> The cause of this is the DefaultProfileInjector in maven-project. It calls
> Xpp3Dom.mergeXpp3Dom with the profile's configuration as dominant DOM, and
> the models configuration as recessive DOM to merge the dominant DOM into the
> recessive one. However, mergeXpp3Dom directly changes the dominant DOM,
> instead of creating a merged copy. Therefor the profiles DOM is changed. If
> this profile is injected a second time, e.g. because of a reactor build, the
> original DOM is gone. Since the changed profile is also saved in the model,
> this often results in the profile DOM (changed by earlier merge) being merged
> into itself (saved in model from earlier merge). Boom -- we get an
> OutOfMemoryError.
> The attached patch changes DefaultProfileInjector by ensuring that dominant
> DOMs are copied before they are passed to Xpp3Dom.mergeXpp3Dom.
