Description

We found that after OOZIE-1978 the attached workflow becomes invalid. Aa we found out the following line brings the problem: https://github.com/apache/oozie/commit/8e9b9042b3270dc5ff975c44a5c977fcc41250e4#diff-a38ae78886b7c3afb711d32cfb4dbbbdR267 . The parameter "okPath" changed from okPath to true.

The following workflow is problematic:

<workflow-app xmlns="uri:oozie:workflow:0.4" name="shell-fork-wf">
    <start to="fork"/>
    <fork name="fork">
        <path start="FA"/>
        <path start="FB"/>
    </fork>
    <action name="FA">
