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

             Summary: Cannot assign value of type java.lang.Object in ternary 
operator with null
                 Key: GROOVY-7507
                 URL: https://issues.apache.org/jira/browse/GROOVY-7507
             Project: Groovy
          Issue Type: Bug
          Components: Static Type Checker
    Affects Versions: 2.4.4, 2.4.3
            Reporter: Mauro Molinari
            Assignee: Cédric Champeau


This seems to be something like a regression of GROOVY-5734.

The following fails in Groovy 2.4.3/2.4.4, while it didn't fail in Groovy 
2.3.11:

{code:title=Bar.java}
package test2;

public class Bar {
}
{code}

{code:title=Foo.java}
package test2;

public class Foo {
        private Bar bar;
        
        public void setBar(Bar bar) {
                this.bar = bar;
        }
        
        public Bar getBar() {
                return bar;
        }
}
{code}

{code:title=Test.groovy}
package test2

import groovy.transform.CompileStatic;

@CompileStatic
public class Test {
        void test() {
                boolean check = true
                Foo foo = new Foo()
                foo.bar = check? new Bar(): null
        }
}
{code}

The assignment to {{foo.bar}} fails with:{{Cannot assign value of type 
java.lang.Object to variable of type test2.Bar}}.

The same heppens if {{Foo}} is written in Groovy instead of Java.
