Are all package name changes related to the issue mentioned in the description?

@olamy
No, of course not, but here I wanted to demonstrate whether commit from Jonathan would be stable after the latest chnages.
I think Jonathan's commit would be fine but it truly provocated the issue in SUREFIRE-1719 and therefore the issue SUREFIRE-1719 should be fixed before the PR #253 . At the Slack we talked about it so that the failed test ForkModeIT_testForkCountTwoNoReuse is related to the same symptoms with reuseForks=false and also we uncovered the root cause https://issues.apache.org/jira/browse/SUREFIRE-1719?focusedCommentId=16977946&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16977946
