Spring Boot EhCache returning stale data

Question

If service been hit after data is been expired. It is returning the old data and then refresing the data in the second hit. This is causing service to fail.

    @Cacheable(value = "tokenCache", cacheManager = "springTokenCacheManager")
    public String getToken(PublicKey publicKey) {....}

Jcache manager bean:

@Bean
  public JCacheCacheManager springTokenCacheManager(
      @Qualifier("tokenCacheManager") CacheManager cacheManager) {
    return new JCacheCacheManager(cacheManager);
  }

@Bean(destroyMethod = "close")
  public CacheManager tokenCacheManager(
      TokenExpiryPolicy tokenExpiryPolicy, CacheEventLogger cacheEventLogger) {

    CacheEventListenerConfigurationBuilder cacheEventListenerConfiguration =
        CacheEventListenerConfigurationBuilder.newEventListenerConfiguration(
                cacheEventLogger,
                EventType.CREATED,
                EventType.UPDATED,
                EventType.EVICTED,
                EventType.EXPIRED,
                EventType.REMOVED)
            .unordered()
            .asynchronous();

    CacheConfiguration<PublicKey, String> cacheConfiguration =
        CacheConfigurationBuilder.newCacheConfigurationBuilder(
                PublicKey.class, String.class, ResourcePoolsBuilder.heap(1))
            .withExpiry(tokenExpiryPolicy)
            .withService(cacheEventListenerConfiguration)
            .build();


    EhcacheCachingProvider provider =
        (EhcacheCachingProvider)
            Caching.getCachingProvider("org.ehcache.jsr107.EhcacheCachingProvider");

  
    CacheManager cacheManager = provider.getCacheManager();

    Cache<PublicKey, String> cache =
        cacheManager.createCache(
                TOKEN_CACHE, Eh107Configuration.fromEhcacheCacheConfiguration(cacheConfiguration));

    return cacheManager;
  }

ExpiryPolicy

@Component
public class TokenExpiryPolicy implements ExpiryPolicy<PublicKey, String> {

  @Override
  public Duration getExpiryForCreation(PublicKey key, String value) {
    Duration expiryDate = getExpiryDate(value);
    log.info("Token expires duration for creation {}", expiryDate);
    return expiryDate;
  }

  @Override
  public Duration getExpiryForAccess(PublicKey key, Supplier<? extends String> value) {
    Duration expiryDate = getExpiryDate(value.get());
    log.info("Token expires duration for access {}", expiryDate);
    return expiryDate;
  }

  @Override
  public Duration getExpiryForUpdate(
      PublicKey key, Supplier<? extends String> oldValue, String newValue) {
    Duration expiryDate = getExpiryDate(newValue);
    log.info("Token expires duration for update {}", expiryDate);
    return expiryDate;
  }

  private Duration getExpiryDate(String token) {
    Duration expiry = Duration.ZERO;
    try {
      DecodedJWT decodedJWT = JWT.decode(token);
      Date expiresAt = decodedJWT.getExpiresAt();
      log.info("Token expires at {}", expiresAt);
      Date currentDate = new Date();
      if (expiresAt.before(currentDate)) {
        log.info("Token expired {}", expiresAt);
      } else {
        expiry = Duration.ofMillis(expiresAt.getTime());
      }
    } catch (JWTDecodeException e) {
      log.error("Exception while decoding JWT token");
    }
    return expiry;
  }
}
