[JIRA] [workflow-plugin] (JENKINS-27927) Some interface idioms do not work in Groovy CPS

Tue, 14 Apr 2015 14:45:00 -0700

Ahh.. in which case I apologies for the miscommunication on my part, I actually tried the Java syntax first - I then reduced the problem to simpler forms to post the issue.

Here is what I tried originally:

interface Foo {
    String name()
}
class Bar implements Foo {
    def String name() {
        return "Ronald"
    }
}

node {
    b = new Bar()
    a = b as Foo

    echo a.name()
}

This doesn't work either and the same exception Cannot invoke method visit() on null object is thrown.

Yet under a groovy console:

interface Foo {
    String name()
}

class Bar implements Foo {
    def String name() {
        return "Ronald"
    }
}

b = new Bar()
a = b as Foo

println a.name()

It works fine. Hence I think it is likely a problem with all uses of interface and why I'm on the lookout for a decent workaround
