Burned by wildcard imports and SwingWorker
The following code usescom.publicobject.swing.SwingWorker
from the Java tutorial:package com.publicobject.demo;
import com.publicobject.swing.*;
import javax.swing.*;
public class HelloWorldWorker extends SwingWorker {
private final JLabel label;
public HelloWorldWorker(JLabel label) {
this.label = label;
}
public Object construct() {
return "Hello World";
}
public void finished() {
label.setText((String)get());
}
}
It compiles fine under Java 5. But in Java 6, it doesn't even compile! The problem is that the two imports conflict - there's my
SwingWorker
, and the one Mustang provides in its javax.swing
package. If you're using SwingWorker
, you should fully qualify your imports now so when Java 6 comes, you're ready.
