> ntroduced support for multiple token verification mechanisms (i.e., PEM,
> jwks) for the same topology (provider instance), falling back to Knox's own
> signing and TLS keys if any of those configured should fail.
> This behavior may not be expected by some, and we should provide the ability
> to control the fallback to the Knox keys.
> To support deployments expecting the previous behavior, there should be a
> provider param for indicating that the new fall-back behavior is desired
> (e.g., instance-keys-fallback=true), which defaults to false.
> Default Behavior:
> * Neither PEM nor jwks URL(s) is configured, attempt verification using (in
> order)
> ** Knox's signing key
> ** Knox's TLS key
> * Only PEM is configured: Knox will attempt verification using ONLY the
> configured PEM
> * Only jwks URL(s) are configured: Knox will attempt verification using ONLY
> the configured jwks URL(s)
> * PEM AND jwks URL(s) are configured: Knox will attempt verification using
> ONLY (in order)
> ** The configured PEM
> ** The configured jwks URL(s).
> instance-keys-fallback=true Behavior:
> * Same as default behavior except that in the cases where PEM and/or jwks
> URL(s) are configured and fail to verify, Knox will subsequently attempt
> verification using (in order):
> ** Knox's signing key
> ** Knox's TLS key
