AuthConfigFactory javadoc indicates methods throw AuthException but method signatures do not

avadoc of four AuthConfigFactory methods indicate that they throw
AuthException (which is a checked exception) but method signatures do not
declare that they throw AuthException, and thus the exception cannot be thrown.
Moreover, the inability to throw this exception, makes it unclear how errors
are to be signaled by these methods.

AuthException although method signature does not declare that it does.
