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

             Summary: Fail to infer the correct type argument when having conditionals and diamond operator
                 Key: GROOVY-10614
                 URL: https://issues.apache.org/jira/browse/GROOVY-10614
             Project: Groovy
          Issue Type: Bug
          Components: Static Type Checker
            Reporter: Thodoris Sotiropoulos


I think this is a regression bug, because Groovy 4.0.2 compiles the program successfully.

{code}
class Foo<T> {}

class Test {
  public static void test() {
    foo((true) ? new Foo<Boolean>() : new Foo<>());
    
  }

  public static void foo(Foo<Boolean> x) {}
  
}
{code}

h3. Actual behaviour

{code}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
test.groovy: 5: [Static type checking] - Cannot call Test#foo(Foo<java.lang.Boolean>) with arguments [Foo<? extends java.lang.Object>]
 @ line 5, column 5.
       foo((true) ? new Foo<Boolean>() : new Foo<>());
       ^

1 error
{code}

h3. Expected Behaviour

Compile successfully

Tested against master (commit: e183dc8e04a8ca8762e85e21ac3ee0c03138b6e1)
