IDE throws a java.lang.ClassCastException on selecting "Tools" -> "Options" from the menu. IDE is launched from NetBeans launcher 1.3 with Aqua look and feel fontsize=11. DOES NOT OCCUR WITH METAL L&F, so could be a bug with JDK?

Can you reliably reproduce the bug? Please also test if the same issue happens with the latest NB 3.5-dev build. Thanks for info
Yes, this bug is reproducable ALWAYS. I simply click Tools, Options, and always get the exception. I will test on NB 3.5-dev build this weekend.
One more piece of info, I am running in MDI mode.
I cannot reproduce it in NB 3.5.
This is already fixed long time ago in main trunk MultiTabbedContainerImpl r.1.33, 11 Apr 2002. There was private field to store UI of type BasicTabbedPaneUI and apparently there is no BasicTabbedPaneUI in Mac OS X. They directly implement TabbedPaneUI
If it is important for you to run S1S 4.1 on Mac OS X I could try to create patch.
As they was no problem with suggested patch for S1S 4.1 (or NB 3.3.2) I will attach patch here. Simply place it to lib/patches.
