[GROOVY-3675] MetaClassImpl invokes call() on binding variable even if it is not a Closure

• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Won't Fix
• Affects Version/s: 1.6.4

Description

The following:

foo = 5
foo()

results in:

Caught: groovy.lang.MissingMethodException: No signature of method: java.lang.Integer.call() is applicable for argument types: () values: []
	at MyScript.run(MyScript.groovy:2)

This is bad for at least two reasons:

• The error message is hard to understand (should be: No signature of method: MyScript.foo() is applicable for argument types: () values: [])
• invokeMethod and methodMissing don't get a chance to intercept the method call

Likely solution: Change line 1093 of MetaClassImpl.java to: if(bindingVar instanceof Closure) {
