Current Behavior
Multiple errors are produced through the collecting process. The errors are caught in the RssFeedListener service are shown in a log trace.

Steps to reproduce
For reproducing the current behavior you need:

• Up and running docker-compose stack
• Run FeedCollectorApplication

Steps to fix
A good practice to fix theses errors could be:

• In a unit test, similar to RssFeedListenerTest, you could reproduce the parser process of a feed through Rome library.
• If the error could be solved, do and pushed it. Otherwise, the feed must be deleted from opml file in the collector artifact.
