Examples of java.security.ProviderException

java.security.ProviderException
A runtime exception for Provider exceptions (such as misconfiguration errors or unrecoverable internal errors), which may be subclassed by Providers to throw specialized, provider-specific runtime errors. @version 1.17, 11/17/05 @author Benjamin Renaud

            assert false : "Should never have reached here";
