Surefire reuseForks bug demo

Build

mvn clean verify

Works

<reuseForks>true</reuseForks>

Doesn't work

<reuseForks>false</reuseForks>

Solution

The solution is to use MAVEN_OPTS="--add-modules .. mvn clean verify" because with reuseForks set to false, the tests will be run inside the same JVM as mvn. Since this JVM is already running, argLine won't have any effect.
