That's bound to cause problems because a lot of code assumes these
arguments here. We shouldn't touch them and instead do as the documentation you
linked suggested:
One of the ways to do this in case of maven-surefire-plugin - is to use
syntax for late property evaluation:
```xml
<argLine>@{argLine} -Xms256m -Xmx800m
-Dmvn.forkNumber=${surefire.forkNumber} -XX:-UseGCOverheadLimit</argLine>
```
