Different complining result between SUN JDK 1.4 and IBM JDK 1.3.1

Question

Hi! I simplifed my code as following:
public class TestException2 {
    public Object test() {
        java.sql.Connection cn = null;       
        try {
             // 1st. close
            cn.close();
        catch (java.sql.SQLException se) {
             // 2nd. close
            cn.close();
        finally {
            return new Object();
}But I get different compiling result betwueen SUN JDK 1.4.2 and IBM JDK 1.3.1 (I have to deploied my app to the websphere 5.0)
In Sun JDK 1.4.2, I only got a warning:
[e:\work\test]javac TestException2.java
TestException2.java:14: warning: finally clause cannot complete normally
        ^
1 warningIn IBM JDK 1.3.1, I got an error:
TestException2.java:10: unreported exception java.sql.SQLException; must be caught or declared to be
thrown
            cn.close();
              ^
1 errorWhat happend? Who is right?
Thank you!
[ I believe the code should not pass the compilation ... ]

Answer 1

Many other people agree with you, including some Sun engineers.
Perhaps Sun just feels an obligation to continue to allow it for legacy reasons.
You might also investigate the compiler that comes with Eclipse.
http://www.eclipse.org/
It has a more flexible approach: for some cases, it lets you decide what is a warning and what is an error.
