Hi -  
I am compiling from source to get a back ported fix going on 1.4.x branch. However, compilation is currently failing now in the gatling-recorder module. Can this be resolved shortly?

**app/gatling (1.4.x) »** mvn clean package -DskipTests

1.4.X branch can only be compiled with JDK6, master can only be compiled with JDK7

I have yet to configure maven-enforcer-plugin for 1.4.X.
