Has anyone seen this before? As far as we can tell from our own code, we are trying to open a .gif at that point, but all the .gif's on the system are valid. We are running jdk 1.3.1 and PJAToolkit 2.4_1.

java.lang.ClassCastException
at com.eteks.awt.PJAGraphicsManager.getImage(java.net.URL) (PJAGraphicsManager.java:804) (pc 86)
at com.eteks.awt.PJAGraphicsManager.getImage(java.lang.String) (PJAGraphicsManager.java:762) (pc 82)
at com.eteks.awt.PJAToolkit.getImage(java.lang.String) (PJAToolkit.java:580) (pc 4)
at javax.swing.ImageIcon.<init>(java.lang.String,java.lang.String) (ImageIcon.java:77) (pc 34)

Has anyone faced a similar case ? I got the following exception stack :

java.lang.ClassCastException
at com.eteks.awt.PJAGraphicsManager.getImage(java.net.URL) (PJAGraphicsManager.java:804) (pc 86)
at com.eteks.awt.PJAGraphicsManager.getImage(java.lang.String) (PJAGraphicsManager.java:762) (pc 82)
at com.eteks.awt.PJAToolkit.getImage(java.lang.String) (PJAToolkit.java:580) (pc 4)
at javax.swing.ImageIcon.<init>(java.lang.String,java.lang.String) (ImageIcon.java:77) (pc 34)
at javax.swing.ImageIcon.<init>(java.lang.String) (ImageIcon.java:103) (pc 3)
...

Could it be possible that the implicit cast is failing ?

in class: PJAGraphicsManager.java
method : public Image getImage (URL url)

java.net.URLConnection conn = url.openConnection();

If the openConnection() failed, we would have got an IOException.
Wouldn't we ?

The statement throwing the exception is this:

return createImage ((ImageProducer)(conn.getContent ()));

What do you think about an explicit cast:

Object content = conn.getContent();
ImageProducer producer;
try {
producer = (ImageProducer) content;
}
catch (ClassCastException e) {
}
return createImage ( producer );
