ElasticSearch Fails To Start
Steps to reproduce
I have seen this issue both on my development machine (Debian 8.1 + testing, Java 1.7.0_75, mvn versions 3.1.0 to 3.3.3) as well as multiple other testing machines. The system appears to start correctly, however when you scroll up in the admin's logs you get this exception and the new admin UI does not work properly (no list of workflows, lists 10+ pages of results which dont work). Previously resolved by clearing my m2 cache, however that is not resolving the issue now.
I could not reproduce this.
Please re-open the ticket if you still get this error.
This exception appears in a couple of other places online, specifically https://groups.google.com/forum/#!topic/elasticsearch/slROQIqCRzU. Looks like it's classloader related, but I have not had any luck manually adding the elasticsearch jar to the Felix jars.
