I have logstash 5 alpha4 installed and when i try to install plugins:
`sudo /usr/share/logstash/bin/logstash-plugin install logstash-patterns-core`
I get this:
```
Validating logstash-patterns-core
Installing logstash-patterns-core
OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000e0a00000, 22544384, 0) failed; error='Cannot allocate memory' (errno=12)
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.

```
It's looks similar to [Logstash 5.0.0-alpha4 - Error while installing plugins #5581](https://github.com/elastic/logstash/issues/5581#issuecomment-232450467)
But no one answered me here, any ideas?
