Description

Closure tries to rsolve a method ot poperty name by first using the MetaClass, second using the owner and thirdly using the delegate. However InvokerHelper.getProperty(owner, property) always returns null if the owner is a script.

This can produce subtle bugs (e.g. when using an Expando object in a script.

exp = new Expando()
exp.a = "x"
println exp.a
exp.b =

{println "called"}

exp.b()
exp.c = {println "a = ${this.a}"}
exp.c()
exp.c = {println "a = ${this.a}"}
exp.c.setDelegate(exp)
exp.c()

produces different output in a script and a program
