Description

The attached propertyaccess.zip contains the following:

src/main/groovy/Widget.groovy

package demo

class Widget {

    static Integer someNumber = 42
}

src/test/groovy/WidgetSpec.groovy

package demo

class WidgetSpec extends spock.lang.Specification {

    void 'test property access'() {
        given:
        Widget.metaClass.getSomeNumber = {
            2112
        }

        when:
        def widget = new Widget()

        then:
        widget.someNumber == 2112
    }
}

That test fails because widget.someNumber is 42. If I edit build.gradle and use Groovy 2.3.9 instead of 2.3.10, the test passes. Is this change in behavior intentional?

Lari thinks that maybe https://github.com/groovy/groovy-core/commit/5e446eca2bae406619d8a6b115af6e4521bed2e4 is relevant.
