• Affects Version/s: 2.4.6

Description

Compiling the following:

IOOBE.groovy

import groovy.transform.TypeChecked

import java.nio.file.Files
import java.nio.file.Paths

@TypeChecked
class IOOBE
{
  def ioobe()
  {
    Files.write(Paths.get('foo.bar'), { ['foo', 'bar'].iterator() });
  }
}

(closure is used to automatically coerce Iterator to Iterable),
produces the following exception during compilation:
