Example 88 with BackingStoreException

use of java.util.prefs.BackingStoreException in project energy3d by concord-consortium.

the class OneInstance method unregister.

When you don't do this then the port number will stay in the preferences so on next start of the application this port number must be validated. So by calling this method on application exit you just save the time for this port validation.
