[GROOVY-5301] closures do not handle 'it' correctly

• Type: Bug
• Status: Closed
• Priority: Minor
• Resolution: Not A Problem
• Affects Version/s: 1.8.5
• Component/s: groovy-jdk
• Labels: closure it
• Environment: Windows command line (to reduce dependencies)

Description

Running the following script shows 'it' as being null:

dec = { it ->
def x = it
return { println "${x--} (was $it)" }
}

def f = dec(2)
f(); f();

Output is:
2 (was null)
1 (was null)

If the 'it' references are changed to 'val', then it works fine - i.e. says '(was 2)'

This also fails when no parameter is used (i.e. defaulting to 'it')
