Investigation findings

When the RC /v0.7/config endpoint returns HTTP 401, the call path terminates silently:

  1. DefaultConfigurationPoller.sendRequest() receives the 401
  2. response.isSuccessful() is false → the response body is logged via a rate-limited warning and the method returns
  3. handleAgentResponse() is never called
  4. RemoteConfigServiceImpl.accept() is never called
  5. FeatureFlaggingGateway.dispatch(ServerConfiguration) is never called
  6. DDEvaluator.accept() is never called
  7. initializationLatch never counts down
  8. DDEvaluator.initialize() times out and returns false
  9. Provider.initialize() throws ProviderNotReadyError — wrong state: should be PROVIDER_FATAL

Fix

Added a NonRetryableErrorListener chain from the RC transport layer up to the OpenFeature provider:

  • ConfigurationPoller (interface): added addNonRetryableErrorListener / removeNonRetryableErrorListener default methods and the NonRetryableErrorListener functional interface
  • DefaultConfigurationPoller: implements the listener list; sendRequest() calls notifyNonRetryableErrorListeners() when response.code() is 401 or 403
  • RemoteConfigServiceImpl: registers a NonRetryableErrorListener that forwards to FeatureFlaggingGateway.dispatchFatalError()
  • FeatureFlaggingGateway: added FatalErrorListener interface plus addFatalErrorListener / removeFatalErrorListener / dispatchFatalError() — no OpenFeature SDK dependency (uses plain int for status code)
  • DDEvaluator: implements FatalErrorListener; on receipt stores the error message and releases initializationLatch; initialize() checks for the fatal message after the latch releases and throws FatalError, causing the OpenFeature SDK to set PROVIDER_FATAL

Test plan

  • Verify unit tests in feature-flagging-api and remote-config-core still pass
  • Confirm that a 401 response to /v0.7/config in the system test causes the provider to enter PROVIDER_FATAL
  • Confirm that a 200 response still causes the provider to enter PROVIDER_READY
  • Confirm that a timeout still causes PROVIDER_NOT_READY (latch not released, configuration.get() is null)

Add PROVIDER_FATAL state propagation for non-retryable RC errors
268fbea 
When the RC endpoint returns a non-retryable 4xx (401, 403), the
OpenFeature provider now transitions to PROVIDER_FATAL instead of
blocking indefinitely or timing out with PROVIDER_NOT_READY.

Code path:
- DefaultConfigurationPoller.sendRequest() detects 401/403 and notifies
  registered NonRetryableErrorListeners
- RemoteConfigServiceImpl registers such a listener and forwards to
  FeatureFlaggingGateway.dispatchFatalError()
- DDEvaluator implements FeatureFlaggingGateway.FatalErrorListener;
  on receipt it stores the error message and releases the initialization
  latch
- DDEvaluator.initialize() throws FatalError after the latch is
  released with a fatal error present
- Provider.initialize() re-throws FatalError (it extends OpenFeatureError)
  causing the OpenFeature SDK to set state to PROVIDER_FATAL

feat(ffe): handle post-init RC fatal errors in DDEvaluator and Provider
23a7c94 
- DDEvaluator.evaluate() now returns PROVIDER_FATAL when fatalErrorMessage
  is set, taking precedence over PROVIDER_NOT_READY and normal evaluation
- Two-arg DDEvaluator constructor (configCallback, fatalCallback) made public
- Provider.buildEvaluator() wires onProviderFatal() as fatalCallback via
  the two-arg constructor; onProviderFatal() emits PROVIDER_ERROR event
- DefaultConfigurationPoller.sendRequest() removes special 404 early return;
  400 and 404 added to isNonRetryableError() so they trigger fatal listener
- Added unit tests for fatal path: onFatalError behavior, evaluate after
  fatal, fatal takes precedence over existing config, callback invocation
@typotter
fix(ffe): update ConfigurationPoller Javadoc to include 400/404 error…
