hmm... seems I can no longer reproduce the problem. actually I check the script:

public class Foo { }

def tripSpecs=[1,2,3]
def bar=[0]
def foo=[1,2,3]

use (Foo) {
  foo.each { line ->
    tripSpecs*.{bar[0] += 1 }
  }
}

which fails at runtime with a groovy.lang.MissingPropertyException: No such property: 1 for class: java.lang.Integer, which is ok, to me, since bar[0]+=1 returns an Integer, which is converted to a string. So we try to do for example 1.1 or 2.1.. which of course fails. With for example

public class Foo {
  static get(Integer i, String j) {j}
}

the program runs fine
