challenges in your swing projects@@

Challenge: layout. If it can take a few hours to implement new biz logic it can take 2 days to get the layout exactly right. Dotnet solutions probably takes half a day only. Sub-panels take memory. WYSIWYG layout? WPF separates layout and code into separate physical files

Challenge: memory consumption is higher in swing than other GUI frameworks. Many times a swing app take up 900MB and will not be able to grow further.

Challenge: threading. Manageable unless messaging rate is very high.
Challenge? robust performance. App should remain fast and responsive in the face of various hazards -- slow DB/network; memory leak; slow action listeners; ....
Challenge? bloated fields and method params
Challenge? memory leak due to listeners. Swing is a memory hog.
Challenge? EDT overloaded? 
Challenge? code duplication -- a lot of similar callbacks
Challenge? a long and ever-growing class with lots of inner classes -- including invokeLater() and callbacks
