Hello,

Has anyone tried jpython out under the jdk1.1.8 port?
I have been playing with jpython under Windows, so I thought
I would try it under FreeBSD.

I downloaded everything last night and got:

[21 ishtar: /home/davidh] % jpython test.py
SIGSEGV   11*  segmentation violation

The test script is here and has been tested under Windows NT with
the jdk1.1.8 and jfc1.1.1:

[22 ishtar: /home/davidh] % cat test.py
import java.lang

import javax.swing.JButton
import javax.swing.JFrame

def exit(event):
        java.lang.System.exit(0)

class App:
        def __init__(self):
                self.frame = javax.swing.JFrame("Quit")
                self.button = javax.swing.JButton("Quit", actionPerformed=exit)

                self.frame.getContentPane().add(self.button)
                self.frame.pack()
                self.frame.setVisible(1)

if __name__ == '__main__':
        App()
