Description

following test throws MissingPropertyException. We somehow fail to resolve static property in super class

package groovy.bugs

public class StaticPropertyInSuperClassBug extends GroovyTestCaseTest {
void testBug () {
new Sub().each

{ it.doIt() }

}
}

class Super {
static final String PROP = "ABC"

def doIt =

{ PROP }

}

class Sub extends Super {
}

groovy.lang.MissingPropertyException: No such property: PROP for class: groovy.bugs.Sub
