If JFileChooser is loaded from the app thread BasicListUI.updateLayoutState
is called at the same time on two threads: main application thread and EDT.
Filechooser updates layout state on EDT after loading the files, at the
same time filechooser dialog is packed and validated on the main thread.
Method updateLayoutState is works with array cellHeights and resets it to
null at a couple of places. So, the main thread is trying to access the
data that is alredy set to null by EDT and we get the NPE.
