Re: Thumbs up for suppressable exceptions in JDK 1.7

Dear All

Was just playing around with suppressable exceptions
in JDK 1.7. This looks like a great improvement for
bug hunting!

Best Regards

Manually Suppressed:
------------------

  public class TestSuppressed {

    public static void main(String[] args) throws Exception {
        try {
            throw new IllegalArgumentException("x");
        } catch (IllegalArgumentException x) {
            x.addSuppressed(new IllegalArgumentException("y"));
            throw x;
        }
    }

  }

gives:

   Exception in thread "main" java.lang.IllegalArgumentException: x
    at TestSuppressed.main(TestSuppressed.java:12)
    Suppressed: java.lang.IllegalArgumentException: y
        at TestSuppressed.main(TestSuppressed.java:14)
        ... 5 more

Automatically Suppressed:
---------------------

   public class TestSuppressed implements AutoCloseable {

      public static void main(String[] args) throws Exception {
        try (TestSuppressed ts=new TestSuppressed()) {
            throw new IllegalArgumentException("x");
        }
      }

      public void close() throws Exception {
        throw new IllegalArgumentException("y");
      }

   }

gives:

   Exception in thread "main" java.lang.IllegalArgumentException: x
    at TestSuppressed.main(TestSuppressed.java:9)
    Suppressed: java.lang.IllegalArgumentException: y
        at TestSuppressed.close(TestSuppressed.java:20)
        at TestSuppressed.main(TestSuppressed.java:10)
        ... 5 more
