The Groovy subclass is called the superclass method that accesses the closure

I have a groovy superclass that looks like this:

class AGroovyClass {
   private String str = "hello"
   void printString(int nTimes) {
     nTimes.times { println str } 
  }        
}

and subclass

class AGroovySubclass extends AGroovyClass {
   // some other subclass methods
}

My client code calls:

new AGroovySubclass().printString(5)

And it really breaks because he says there is no such "str" โ€‹โ€‹property for AGroovySubclass

I would have thought, since the printString method is in AGroovyClass, it should have no problem accessing the "str" โ€‹โ€‹property, but I'm sure I'm wrong. If I wanted to keep "street" personal, what is the appropriate way to make it work?

This is an old bug with the private access modifier. It works if you define str protected. http://jira.codehaus.org/browse/GROOVY-2433



edit: Can you avoid the closure, use a for loop instead? Not so cool, but it works :)
