[GROOVY-4497] IllegalAccessError when accessing base class property with "super.propertyName"

• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Fixed
• Affects Version/s: 1.7.5
• Fix Version/s: 1.7.6, 1.8-beta-3
• Component/s: Compiler
• Assignee: Roshan Dawrani

Description

The following code...

class Base {
  def x = 1   
}

class Derived extends Base {
  def x = 2 
  
  def foo() { println super.x }
}

new Derived().foo()

...produces the exception shown below. Problem goes away if base class declares a field rather than a property, or when derived class uses "super.getX()".
