[type inference] Type mismatch: cannot convert error - javac compiles

Test case to reproduce:
```
interface V {}
abstract class A implements V {
public static A getA(T value) {
return null;
}
}

interface J {}
interface K {
X foo();
}
// javac compiles while ecj gives the following error
public class X {
public A> bar() {
return A.getA( // ERROR: Type mismatch: cannot convert from A to A>
new K() {
@Override
public X foo() {
return null;
}
});
}
}

```
ecj throws "ERROR: Type mismatch: cannot convert from A to A>"

@srikanth-sankaran could you please have a quick look if time permits? thanks
