Hello,

When trying to install the logstash-filter-elasticsearch plugin (v3.1.4) I get the below exception:  
I have tried installing the zip and the gem file. My logstash version is 5.4.0.

java/util/Hashtable.java:459:in `put': java.lang.NullPointerException from java/util/Properties.java:166:in`setProperty'

In order to dismiss issues wether what I did was incorrect I tried this at home on my own machine (using the same code) and it installed without any problem.

I get this error after defining http\_proxy environment variable.

Any pointers/ideas?

Regards benny
