How to pass JVM args (-D) to Integration Tests

I am trying to migrate from another plugin to ```integTest``` and trying to root cause some failures in integration tests which did not happen before.

Is there an example on how to pass JVM args (```-D``` parameters) to Integration Tests? 

Also do ```System.setProperty``` and ```System.getProperty``` need some configuration to make it work for integration tests or they work out of the box ?
