Example adapted from bug 97027. Several of the calls to test() are flagged by
javac ("reference to test is ambiguous, both method test() in xy.AA<xy.CC> and
method <T>test() in xy.BB match"), but accepted by Eclipse.

public class Try {
  public static void main(String[] args) {
    BB bb= new BB();
    
    AA<CC> res= bb.test(); // eclipse accepts, javac rejects
    AA<Object> res1= bb.test(); // different errors
    BB res2= bb.test(); // eclipse accepts, javac rejects
    AA res3= bb.test(); // eclipse accepts, javac rejects
    bb.<Object>test(); // both accept
    
    AA<CC> a= bb;
    a.test(); // both accept
  }
}

class AA<T> {
  public AA<Object> test() { System.out.println("AA<T>#test()"); return null; }
}
class BB extends AA<CC> {
  public <T> BB test() { System.out.println("BB#test()"); return null; }
}
class CC {}
