> In DataPool, following can be done to reduce memory usage:
> * -ArtifactDescriptor key does not have to be Artifact instance, is really
> just GACEV needed (is identity)- WRONG, it must be Artifact. Still, some
> improvement is done introducing new key type.
> * ArtifactDescriptors could have "interned" the List<Dependency> fields as
> well
> Latter is done and controlled by two new configuration properties:
> * {{aether.dependencyCollector.pool.internArtifactDescriptorDependencies}}
> defaults to {{false}}
> *
> {{aether.dependencyCollector.pool.internArtifactDescriptorManagedDependencies}}
> defaults to {{true}}
> Having true/true tremendously improve memory consumption but increases
> runtime.
