Description

This issue is raised based on dev mailing list discussion here: http://markmail.org/message/ksngkezqgqazpz5q

Here are the code snippets that demonstrate the issue with constructor call generation when anonymous inner classes and closure are used together.

1)

interface X{}

final double delta = 0.1
(0 ..< 1).collect { n ->
    new X () {
        Double foo () {
            delta
        }
    }
}

fails with

Caught: groovy.lang.GroovyRuntimeException: Could not find matching constructor for: TryGroovy$1(TryGroovy, java.lang.Double)

2) Seems like there is some mix-up with the variables used from the enclosing context. In this snippet, I use 2 variables from enclosing context, and both become part of constructor call that fails.

interface X{}

final double delta1 = 0.1
final double delta2 = 0.1
(0 ..< 1).collect { n ->
    new X () {
        Double foo () {
            delta1 + delta2
        }
    }
}

fails with:

Caught: groovy.lang.GroovyRuntimeException: Could not find matching constructor for: TryGroovy$1(TryGroovy, java.lang.Double, java.lang.Double)
