[JENKINS-38945] Pipeline script doesn't find method with explicit parameter type

Pipeline scripts fail to find method declaring parameter type. The script below will fail to execute "doStuff", with NoSuchMethodError.

This used to work, but rolling back security and groovy didn't help, and utility steps (which defines readMavenPom) wasn't available for rollback. On a simple test, "Integer n" works as a type parameter, so this might well be specific to the object returned by readMavenPom().

import org.apache.maven.model.Model


stage ("initial") {

    node ('mesos') {

       git url: 'https://github.com/jglick/simple-maven-project-with-tests.git'



Model pom = readMavenPom()

echo "Class of pom is ${pom.class}"

doThings(pom)

doStuff(pom)

    }

}

def doThings(pom) {

    echo "Got something"

}

def doStuff(Model pom) {

    echo "Got pom"

}
