I am sorry, I am not able to reproduce this issue. Are you still able to reproduce it? If so, could you, please, 
describe exact steps to reproduce?

I am probably able to workaround this issue, but I would like to have a test-case to be sure. Thank you in advance.
Comment 3 Jan Stola 2008-09-08 16:37:31 UTC 
I have implemented the mentioned workaround.

hi i was playing with the jide commons (open source version) https://jide-oss.dev.java.net/
you can reproduce this exception as,

open a new java application
create a new JFrame
put a JideTabbedPane (i put this component to the palette earlier)
put a JPanel on the JideTabbedPane
click the tab header for rename the tab name
enter a new value this makes Jpanel unvisible
and try to resize the JideTabbedPane,
i get always by this way...

Thank you for interest.
