> The getCredentialForCluster(String, String) method of DefaultKeystoreService
> invokes checkCache(String, String) and addToCache(String, String) without any
> synchronization, despite the comments on those methods indicating that they
> are only called within critical sections of other methods. This method should
> be synchronized similar to what is done for the
> addCredentialForCluster(String, String, String) and
> removeCredentialForCluster(String, String) method implementations therein.
