Why an each loop in a Jenkinsfile stops at first iteration

Question

Here is the content of my Jenkinsfile :

node {
    // prints only the first element \'a\'
    [ \'a\', \'b\', \'c\' ].each {
        echo it
    }
}

Thanks to @batmat on #jenkins IRC channel for answering this question!

It's actually a known bug : JENKINS-26481.
