Description

The script

def list = [2, 3, 5]
def c = {it < 5}

c.metaClass = new ExpandoMetaClass(c.class, false)
c.metaClass.isCase = {p -> true}
c.metaClass.initialize()

assert c.isCase(5) == true
assert [2, 3] == list.findAll(c)
assert [2, 3, 5] == list.grep(c) // fails

throws an AssertionError.

It seems that InvokerHelper.getMetaClass does not respect per-instance MetaClasses.
