Steps to reproduce:

1. Configure Periodic Reincarnation to restart jobs with RegEx "some string"
2. Create FreeStyle Job that outputs "some string" and exits 1
3. Create Pipeline Job that outputs "some string" and exits 1
4. Run both jobs

FreeStyle job is restarted, Pipeline Job is not.

Detailed job configs in my testing:

FreeStyleJob shell step:

echo "some string" ; exit 1

PipelineJob script:

node {
    stage('Test') {
        echo 'some string'
        sh "fail now"  //bad command
    }
}
