Bug 258167

The "assign result value to a new variable" hint sometimes does not produce the correct type for the variable, consider:
---
import java.util.Map;

public class InferTest {
    void test(Map<? extends String, ? extends Number> map) {
        map.entrySet();//assign return value to a new variable here
    }
}
---

The "assign return value to a new variable" will produce:
---
Set<Entry<? extends String, ? extends Number>> entrySet = map.entrySet();
---

Which won't compile:
---
InferTest.java:7: error: incompatible types: Set<Entry<CAP#1,CAP#2>> cannot be converted to Set<Entry<? extends String,? extends Number>>
        Set<Entry<? extends String, ? extends Number>> entrySet = map.entrySet(); //assign return value to a new variable here
  where CAP#1,CAP#2 are fresh type-variables:
    CAP#1 extends String from capture of ? extends String
    CAP#2 extends Number from capture of ? extends Number
1 error
---

Inferring this would be more appropriate:
---
Set<? extends Entry<? extends String, ? extends Number>> entrySet = map.entrySet();
---
