Having an issue with LS 5 alpha4: Trying to install any plugins throws an install error, resulting in a retry loop.

I tried to do this first of all with a local .gem, however packaged plugins are also producing the same error.

e.g.,

> `# /usr/share/logstash/bin/logstash-plugin install logstash-filter-anonymize`  
> Validating logstash-filter-anonymize  
> Installing logstash-filter-anonymize  
> Error Bundler::InstallError, retrying 1/10  
> An error occurred while installing logstash-core-event-java (5.0.0.pre.alpha4), and Bundler cannot continue.  
> Make sure that gem install `logstash-core-event-java -v '5.0.0.pre.alpha4'` succeeds before bundling.

Any ideas?

Ubuntu 14.04 amd64  
Logstash 1:5.0.0~alpha4-1  
openjdk-8-jre-headless 8u91-b14-0ubuntu4~14.04

Just adding in a "me too" here.

Backed up to logstash-5-0-0-alpha3 and was able to install the logstash-input-beats plugin without any issue.
