Ended up apt-get remove --purge logstash and re-installed. Now it works.

thanks for the report @ageis - we actually spotted a problem with the date filter v3.1.4 that is actually missing jars. We yanked that version and published v3.1.5. Could you verify which version of the plugin you have installed now after your purge and if you don't have v3.1.5, I suggest you update it.

closing this.

@colinsurprenant all good. I updated to 5.3.2 today and I will just note that it's kind of annoying that I have to reinstall non-default plugins (such as logstash-filter-multiline, logstash-output-riemann) on every upgrade. It would be cool if there was some way those were preserved in the environment when Logstash is updated via apt.

@ageis great! for the plugin update, interesting idea: I would suggest you create an issue about it in the main logstash repo!
