Bug 81618

Description Joe Bowbeer 2004-12-19 16:19:26 EST

The following code triggers a type warning in Eclipse 3.1M4.
Neither Eclipse 3.1M3 nor javac emit a warning, nor should they.

import java.util.concurrent.Callable;
public class TypeWarningBug {
  public static void main(String[] args) throws Exception {
    Callable<Integer> integerCallable = new Callable<Integer>() {
      public Integer call() {
        return new Integer(1);
      }
    };
    System.out.println(integerCallable.call());
  }
}

Type safety: The return type Integer of the method call() of type new
Callable<Integer>(){} needs unchecked conversion to conform to the return type V
of inherited method

To silence, disable "Unsafe type operation involving raw types" in JSK 5.0
compiler options.
