Hi,

I got a Logstash who work well on local docker.  
When i use docker on Azure, Logstash freezes during initialization. I just got these logs :

> Using bundled JDK: /usr/share/logstash/jdk  
> OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

Do you know where this might come from?

Thx you a lot
