-------------------------------------

             Summary: Using with method with a closure that references a protected property produces ClassCastException
                 Key: GROOVY-7996
                 URL: https://issues.apache.org/jira/browse/GROOVY-7996
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 2.4.7
            Reporter: Graeme Rocher


The following example:

{code}

class Foo {
    Object propertyMissing(String name) {
         return "stuff"
    }
    
    void build(Closure callable) {
         this.with(callable)
    }
}

@groovy.transform.CompileStatic
class Bar {
    protected List bar = []
    
    boolean doStuff() {
        Foo foo = new Foo()
        foo.build {
           return bar.isEmpty() 
        }
    }
}

new Bar().doStuff()
{code}

Produces 

{code}
java.lang.ClassCastException: java.lang.String cannot be cast to java.util.List
	at Bar$_doStuff_closure1.doCall(ConsoleScript3:19)
	at Bar$_doStuff_closure1.call(ConsoleScript3)
	at org.codehaus.groovy.runtime.DefaultGroovyMethods.with(DefaultGroovyMethods.java:242)
	at Bar.doStuff(ConsoleScript3:18)
	at Ba
{code}

The equivalent code without CompileStatic prints:

{code}
Result: false
{code}

The behaviour of both should be he same IMO
