Just to keep you informed, this problem occurs because of a change in the behaviour of Groovy's findAll() method. One workaround is to copy the collection before doing a findAll():

def tmp = []
obj.items.each { tmp << it }
tmp.findAll { ... }

For more efficient execution, write a static method that iterates over the collection and explicitly adds found items to a list. In effect, write your own implementation of findAll().

With the top of the GROOVY_1_6_0 branch, this application is now working properly.
