public void refresh()

Overrides javax.security.auth.login.Configuration.refresh.

Doc from javax.security.auth.login.Configuration.refresh.

Refresh and reload the Configuration.

This method causes this Configuration object to refresh/reload its contents in an implementation-dependent manner. For example, if this Configuration object stores its entries in a file, calling refresh may cause the file to be re-read.

The default implementation of this method does nothing. This method should be overridden if a refresh operation is supported by the implementation.
