I've got a weird problem with drag and drop in Java 1.6.0_03. If I use drag and drop to move nodes around in a tree, there are references kept to my view, keeping it from being GC'ed. I repeatedly tested this with a profiler, and without dragging the view is GC'ed. Once dragged/dropped there are stuck references. I would really like some tips on this.

The only thing I do is subclass TransferHandler that overrides various methods like createTransferable( JComponent), canImport( TransferSupport) and importData(TransferSupport).

This is the most puzzling path to one of the GC roots:
MyApplication-> MyDesktopPane -> javax.swing.JEditorPane -> javax.swing.TransferHandler$SwingDropTarget -> javax.swing.TramsferHandler$DropHandler -> javax.swing.TransferHandler$TransferSupport -> my tree

My application has a JDesktopPane, which holds a JEditorPane to show some news from our website. This component has NOTHING to do with that tree whatsoever. That tree is in an MDI view.
