Paho on compact Java profiles

We would like to use Paho 1.2.4 in a IoT GW running Azul's JRE8 compact3 profile. We took the jar from maven central and found that the manifest has Java 7 as the required execution environment.

The error message when our OSGi containers starts is
```
The bundle org.eclipse.paho.client.mqttv3 cannot be resolved because requires Execution
Environment(s) [(&(osgi.ee=JavaSE)(version=1.8))], which is/are not available in the
framework Execution Environment(s) [OSGi/Minimum-1.0,OSGi/Minimum-1.1,OSGi/Minimum-
1.2,JavaSE/compact1-1.8,JavaSE/compact2-1.8,JavaSE/compact3-1.8].
```

We cloned, removed the entry from manifest, and rebuilt it to make it work on compact3 JRE. I am not sure if this change is a license violation and I would like to ask what others did to make it work on compact profiles.

* As Paho is meant for IoT devices and since such devices are expected to have compact profiles, can Paho remove the BREE?
* If Paho cannot change it, does it attribute to license violation if we build it locally (after changing the manifest) and use it?
