pzampino opened a new pull request #264: KNOX-2233 - DefaultKeystoreService getCredentialForCluster uses cache… URL: https://github.com/apache/knox/pull/264 … without synchronization ## What changes were proposed in this pull request? Added synchronization to getCredentialForCluster(String, String) since it uses/updates the cache (e.g., checkCache(String, String), addToCache(String, String, String)). At a minimum, this avoids potential repeated unnecessary keystore file accesses for the same alias. ## How was this patch tested? Performed some manual testing, but since the overall behavior should not change, ran all existing tests as validation.
