Description

For reference : http://groovy.329449.n5.nabble.com/StackOverflowError-when-dispatching-to-super-td4572268.html

If a package protected method written in a Java class is overriden in a Groovy class and that method calls super.method(), Groovy throws a stack overflow :

Parent.java
class Parent {
   void someMethod(String param) { ... }
}
Child.groovy
class Child {
   void someMethod(String param) { super.someMethod(param) }
}

Adding a public or protected modifier to the super class solves the problem.
