--------------------------------
Fix Version/s: (was: Issues to be reviewed for 4.x)
> Memory leak in StringSearchModelInterpolator
> --------------------------------------------
>
> Key: MNG-5205
> URL: https://issues.apache.org/jira/browse/MNG-5205
> Project: Maven
> Issue Type: Bug
> Components: Inheritance and Interpolation
> Affects Versions: 3.0.3
> Reporter: Jesse Glick
> Assignee: Kristian Rosenvold
> Priority: Minor
> Attachments: x.diff
>
>
> {{StringSearchModelInterpolator}} abuses {{WeakHashMap}}; the {{Field}}
> values of {{fieldsByClass}} hold hard references to the {{Class}} keys,
> making it useless. Thus if you passed any {{Class}} to it, that class and its
> {{ClassLoader}} and the transitive static graph therefrom would never be
> collectible.
> Anyway a cache is unnecessary, since {{Class}} does its own caching of fields!
> Also removing the ill-conceived {{fieldIsPrimitiveByClass}} - not a memory
> leak, but likely unnecessary complication.
> The class is deprecated anyway, but just in case it is used by someone it
> should be fixed.
