Description

The following code produces an error

static final String A = 'a'

    void testA() {
        def closure = {
            println A
        }
        closure()
    }
    void testC() {
        println(A)
        def closure = {
            println AbstractClass.A
        }
        closure()
  }

class ConcreteClassTest extends AbstractClassTest {
    static final String B = 'b'

    void testB() {
        println(B)
        def closure = {
            println B
        }
        closure()
    }
}

If I run ConcreteClassTest, testB and testC works fine but testA throws an exception.

The stacktrace is:

groovy.lang.MissingPropertyException: No such property: A for class: ConcreteClass
