> The WeakZipFile#entries() method is used in several places when there's a need to iterate through bundle resources.
> That can happen quite a lot of times if there are multiple extenders.
> Caching this value would allow:
>   * avoid scanning all bundles multiple times, especially when they are resolved / started
>   * given it mostly happen when the bundle is resolved or started, using a SoftReference makes sense to not consume memory while still providing a good caching behaviour
