in RefreshScopedResolverTest to capture each property’s prior value before
overwriting it, then restore that value in finally; clear a property only when
its original value was absent.

icms.security.jwt.trusted-issuers[] was flattened into an immutable map in AuthManagerResolver's constructor and baked into the SecurityFilterChain at startup, so a ConfigMap edit was accepted by the reload machinery and then silently ignored. Adding an issuer had no effect, and — more importantly — removing one appeared to revoke trust but did not. Mark TrustedJwtIssuerProperties @RefreshScope and make authenticationManagerResolver() @RefreshScope, following the @bean + @RefreshScope pattern already used by TelemetryConfiguration and EventFormatConfiguration. The trusted-issuer set is derived inside the bean method, which a refresh re-invokes, so the existing injected handle picks up the new set without a restart. The primary and legacy admin issuers stay @Value-bound at construction; only trusted-issuers[] participates in refresh. With trusted-issuers[] unset or unchanged, behavior is identical to before.

Summary
Makes
icms.security.jwt.trusted-issuers[]take effect on a config refresh instead of only at startup.TrustedJwtIssuerPropertiesandauthenticationManagerResolver()both become@RefreshScope. If you don't settrusted-issuers[], nothing changes.Additional Details
AuthManagerResolvertookTrustedJwtIssuerPropertiesin its constructor and immediately flattened it into aCollections.unmodifiableMapon afinalfield. It never kept a reference to the properties bean, so re-binding that bean later had no effect.authenticationManagerResolver()then built oneJwtAuthenticationProviderper issuer into aHashMapand closed over the resultingJwtIssuerAuthenticationManagerResolverin a lambda, whichSecurityConfiguration.filterChain(...)injected into theSecurityFilterChainat startup.The result: editing
trusted-issuers[]in a ConfigMap looked like it worked. The reload fired, nothing errored, and the accepted issuer set never moved. Adding an issuer left its tokens on 401. Removing one left its tokens still accepted — that's the case that actually matters, because it means revoking trust in an issuer silently doesn't happen.The fix builds the issuer set inside the bean method and lets
@RefreshScopere-invoke it, which is the same@Bean+@RefreshScopepatternTelemetryConfiguration.telemetryEventClientandEventFormatConfiguration.eventFormatalready use:AuthManagerResolverkeeps the properties reference and the@Valueissuer strings as fields instead of flattening them in the constructor.jwtResolver(...)now takes the map it should use.TrustedJwtIssuerPropertiesgets@RefreshScope, which every other properties class in icms-core already has (IcmsConfigurationProperties,NgcConfigurationProperties,ByocConfigurationProperties,NatsConfigurationProperties,DbConfigurationProperties,InstanceTypeConfigurationProperties).SecurityConfigurationdoesn't need to change. TheAuthenticationManagerResolverit holds is a per-request lambda, so refreshing that one bean is enough — the filter chain never has to be rebuilt.For the Reviewer
The primary
issuer-uriand the legacyadmin-issuer-uriare still@Value-bound at construction and don't move for the life of the context. Onlytrusted-issuers[]refreshes. The primary issuer is still registered first and unconditionally, andaddTrustedIssuer's skip/dedupe/conflict handling is untouched.Two choices worth a second opinion:
NimbusJwtDecoder.withJwkSetUri(...)fetches lazily on first use, so rebuilding decoders does no network I/O, and a cache would need pruning logic for no real gain.One thing that isn't obvious from the diff: the resolver bean is a lambda behind an interface, which is an awkward shape for a scoped proxy. It does work, and
TrustedIssuerRefreshTestexercises it against the real beans.For QA
AuthManagerResolverTestgets four cases for what a rebuild produces: issuer added at runtime becomes trusted, issuer removed stops being trusted, the primary issuer survives a rebuild, and a conflicting JWKS throwsIllegalStateExceptionnaming the issuer. These call the factory method directly.TrustedIssuerRefreshIntegrationTestis new. It extendsIntegrationTestand drives a realContextRefresher.refresh()over the real beans, through the same resolver handle the filter chain holds — add, refresh, trusted; remove, refresh, revoked. It isn't redundant with the tests above: those pass whether or not the@RefreshScopeannotations are there, so without this one, deleting an annotation would put the bug straight back. I checked by deleting@RefreshScopefromauthenticationManagerResolver()— this test fails and nothing else does.70 tests, 0 failures.
--test_env=HOMEis worth knowing about. Bazel doesn't passHOMEthrough to tests, so thedockerCLI can't find its compose plugin under~/.docker/cli-plugins,IntegrationTest's local-compose probe fails, and it falls back to containerised compose which then dies. Without that flag every Testcontainers test in the repo fails locally. That's not specific to this PR, but it cost me a while to spot.Two other things future refresh tests will hit.
ContextRefresher.copyEnvironment()keeps onlycommandLineArgsanddefaultProperties, so everything@SpringBootTest(properties = ...)inlines —spring.profiles.activeincluded — disappears mid-refresh andValidateEnvironmentPostProcessorfails it; the fix isspring.cloud.refresh.additional-property-sources-to-retain. AndIntegrationTest.Initializerapplies its values throughTestPropertyValues, which lands in a source namedtestthat also isn't retained — harmless here, since beans rebind from the original environment, but it would matter if a test needed those values during the re-read.Also ran it against a live SIS with a jar built off this branch.
jwks_hitsis the signal — SIS only fetches an issuer's JWKS once that issuer is trusted:Same pid throughout, so no restart.
