Detailed Description

Factory class for initializing JFileChooser instances in a background thread.

It is a known issue that on Windows a JFileChooser can take an indeterminate amount of time to initialize. Therefore when a JFileChooser is initialized on the EDT there is the potential for the UI to appear hung while initialization is occurring.

Initializing a JFileChooser in a background thread should prevent the UI from hanging. Using this Factory class at component construction time should allow enough time for the JFileChooser to be initialized in the background before the UI user causes an event which will launch the JFileChooser. If the JFileChooser is not initialized prior to the event occurring, the EDT will be blocked, but the wait cursor will appear.
