Comment 1 Jan Zajicek 2001-07-12 15:55:06 UTC

The behaviour has changed, see following output. In build b70 it
thrown mentioned exception, but in build b71 is everything ok again,
so problem had to be on jdk side and in build b71 seems to be fixed.

b71:

ImageIcon instance: javax.swing.ImageIcon@6e588e
Image instance, will be passed to setIconImage:
sun.awt.motif.X11Image@77e5d4

b70:

ImageIcon instance: javax.swing.ImageIcon@21e7ad
Image instance, will be passed to setIconImage:
sun.awt.motif.X11Image@711970
