-----------------------------------------

             Summary: Closure in parent class can't access private method in 
same class when called from a child class
                 Key: GROOVY-10723
                 URL: https://issues.apache.org/jira/browse/GROOVY-10723
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 4.0.4, 3.0.12, 2.5.18
            Reporter: Leonard Brünings


Private method of parent class can't be accessed by closure when called from a 
child class:

{code:groovy}
class Child extends BaseClass {
    static void main(String... args) {
        println new Child().doStuff([1,2])
    }
}

class BaseClass {
    private int helper(int a) {
        a + 1
    }
    
    def doStuff(List<Integer> numbers) {
        numbers.collect {
                helper(it)   
        }
    }
} 
{code}

When using a classical foreach loop it works
{code:groovy}
class Child extends BaseClass {
    static void main(String... args) {
        println new Child().doStuff([1,2])
    }
}

class BaseClass {
    private int helper(int a) {
        a + 1
    }
    
    def doStuff(List<Integer> numbers) {
        def result = []
        for (int it in numbers){
                        result << helper(it)
        }
        result
    }
}
{code}

Removing the {{private}} modifier also fixes this problem.
