Fresh install of Jenkins 2.7.4, with Pipeline installed (attached about.md)

Using Groovy tuple expressions in Pipeline currently throws:

 
                                                                Started by user anonymous
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

Full console output attached.

Sample Pipeline to reproduce the issue:

 
                                                                def tupleFunc() {
    ["a","b"]
}

node {
    (tA, tB) = tupleFunc()
    
    echo "tA: $tA"
    echo "tb: $tB"
}
