>
> When DefaultLegacySupport is used in conjunction with thread pools
> (ThreadPoolExecutor for example), MavenSession instance is essentially leaked
> via InheritableThreadLocal used by DefaultLegacySupport and will not be
> released to garbage collection until pooled thread is stopped and it's thread
> locals are cleaned up. This can result in excessive memory usage because repo
> system cache can be quite big. See also MNG-4860
