Never change the generics types of a cached class node!
Raw
nasty.groovy
// This is very WRONG because it changes the generics type of the primary class node.
// It means that future instances of ArrayList without generic types specified would be ArrayList<Foo>
def listenerListType = ClassHelper.make(ArrayList)
listenerListType.setGenericsTypes(types)
// Instead, you MUST acquire a class node for which the redirect class node is the primary node
// This can be easily done using the getPlainNodeReference() method
def listenerListType = ClassHelper.make(ArrayList).plainNodeReference
listenerListType.setGenericsTypes(types)
// Not doing so can lead to very nasty and difficult to debug side effects!
