    Description

      KeyProviderFactory uses ServiceLoader framework to load KeyProviderFactory

        private static final ServiceLoader<KeyProviderFactory> serviceLoader =
            ServiceLoader.load(KeyProviderFactory.class);
      

      The ServiceLoader framework does lazy initialization of services which makes it thread unsafe. If accessed from multiple threads, it is better to synchronize the access.
      Similar synchronization has been done while loading compression codec providers via HADOOP-8406.
