Review comment:
       Throwing any exception would also stop the minicluster shutdown process, 
unless you catch it at the caller.
   
   We should make sure that shutdownMiniCluster() will get called even if 
confirmStoreRefCountLeak() fails.
   
   ```
   @AfterClass
   public static void shutdown() {
     confirmStoreRefCountLeak();
     shutdownMiniCluster();
   }
   ```
