Issue481990

This simple script generates an infinite series of
warnings:

# Start of script.
from pawt import swing
import java

class SwingApplication:
    def __init__(self):
        frame = swing.JFrame("SwingApplication");
        frame.pack();
        frame.setVisible(1);


app = SwingApplication()
# End of script.

Here are the warnings:

over and over. I just downloaded and installed the
latest version of jython running on top of the Java 2
SDK beta 1.4 on Red Hat Linux 6.1.  I also got these
warnings during installation.

Thanks,

I will blame JDK1.4 on linux for this. The message is 
clearly about some new 1.4 feature which jython does not 
use at all. The windows version of 1.4 beta works 
flawlessly with jython.

I will close the bugreport because I fail to see how we can 
do anything about it. You might want to try a JDK1.3 
instead.
