I have installed SwingX into my component palette. After upgrading my OSX java to jdk 6u22 the whole IDE is not reacting and must be killed until I delete in .netbeans dir the entry of swingx lib for the palette. Others have reported in netbeans forum that this is happening also on Linux and Windows after the update.
