> While looking at SENTRY-1907 I noticed another thing.
> {{sentryStore.retrieveFullPathsImage()}} uses {{Map<String, Set<String>>}} as
> a snapshot representation. This isn't needed since {{Map<String,
> Collection<String>>}} is sufficient and we can represent it using ArrayList.
> This is much more efficient representation.
