[GROOVY-7115] @CompileStatic: Chained assignment to delegate property broken

• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Fixed
• Affects Version/s: 2.3.7
• Fix Version/s: 2.4.0-beta-4
• Component/s: Static compilation
• Environment: JDK 7u55 on Win7 x64, IntellJ Idea 13.1.5

Description

This script failes, unless @CompileStatic is removed:

import groovy.transform.CompileStatic

test()

@CompileStatic
void test() {

    def obj = new DelegateClass()
    obj.with {
        def locl = prop = "XYZ"
        assert locl == prop
    }
}

class DelegateClass {
    String prop
}

Decompiling the class file shows that the inner, right-most assignment to the property of the closure delegate produces a constant null result instead of passing the right hand side result through all chained assignments.
