Hi, 

Thank you all for the great logstash plugin.

I'm trying to extend the plugin but when I use Java 8 code with Jave 8 features I can't compile the plugin. I get the following error:

"

Restricted to JDK 1.7 yet X contains X.class targeted to JDK 1.8

"

I noticed that if I change the java.level in the pom file to java.level=8 it is working and I won't get any error. Any reasons why it is set to java.level=7? If yes is there any other way to fix it?

Thanks
