Need Help in Implementing patching of Surefire JUnit Parallel Execution Parameters

Hi Team, 

Not sure if this is the correct platform to reach out for help regarding Surefire/Failsafe plugin.

I'm currently creating a package from where I would want to set JUnit parallel execution parameters like below :

<parallel>classesAndMethods</parallel>
<threadCountClasses>1</threadCountClasses>
<threadCountMethods>1</threadCountMethods>
<perCoreThreadCount>false</perCoreThreadCount>

I'm planning to use Instrumentation API to inject these parameters. I tried to find the correct place where I can do so, but failed to find one.

Please point me to a class from where these value are being honoured So that I could inject these parameters there. You could also suggest me a way to set these values apart from adding them to <configuration> element.

Thanks.
