Description

The script:

#!/usr/bin/env groovy
println()

works fine. However the script:

#! /usr/bin/env groovy

testList = [ 1, 2, 3, 4, 5 ]

testList.each { test |
println()
}

fails with the message:

Caught: groovy.lang.GroovyRuntimeException: Could not find which method to invoke from this list: [org.codehaus.groovy.runtime.NewInstanceMetaMethod@94884d[name: println params: [class java.lang.Object, class java.lang.Object] returns: void owner: class org.codehaus.groovy.runtime.DefaultGroovyMethods], org.codehaus.groovy.runtime.NewInstanceMetaMethod@84da23[name: println params: [class java.lang.Object, class java.io.PrintWriter] returns: void owner: class org.codehaus.groovy.runtime.DefaultGroovyMethods]] for arguments: []

at trial.run(/home/users/russel/Progs/Groovy/BugTests/./trial.groovy:5)
at trial.main(/home/users/russel/Progs/Groovy/BugTests/./trial.groovy)

using println("") sort of cures the problem.
