Logstash 5.0.0 alpha2 won't start with RMQ output

Unsure if this is a Logstash or RMQ plugin issue.

Since upgrading from LS 5.0.0 alpha1 to alpha2, Logstash is aborting startup if the RMQ output w/SSL is enabled.

Pipeline aborted due to error {:exception=>java.security.NoSuchAlgorithmException: true SSLContext not available < snip >

Ubuntu 14.04 amd64
Logstash 1:5.0.0~alpha2-1
logstash-output-rabbitmq 3.0.9
openjdk-8-jre-headless 8u91-b14-0ubuntu4~14.04

What other info do I need to provide to get to the bottom of this?


Update to this: Logstash still aborts on startup with the same error while testing with RMQ SSL disabled.

Does anyone have any idea here? I'd like to know if it's logstash or the plugin that's failing so I can open an issue in the correct place.

This error means that Logstash alpha 2 is completely unusable in our dev environment due to our reliance on queues.
