Reveals slow palette content creation (i.e. loading classes and BeanInfos for items in palette). The snapshots show various origin - (1) showing the palette, (2) expanding some category, (3) finding layouts in the palette (for Set Layout action or when a custom layout manager is used in a loaded form).

(1) and (2) could possibly be done on background, updating the palette when complete.

(3) must be done synchronously when the GUI builder needs to find out what layout managers are registered in the palette. Here some faster way of determining this would be desirable.

Comment 4 Tomas Pavek 2011-02-01 16:54:43 UTC 
Palette loading was re-planned off AWT thread, I think for 6.9.

It became a great source of deadlocks when the bug in JDK 6 u21 and u22 appeared, see bug 187697.

Anyway, I think we can mark this as fixed.
