   > Are the two removed null checks not needed?
   
   @jnturton Yes, they are redundant. 
   ``` java   
           if (locatorPlugins != null) {
             bootstrapPlugins.putAll(locatorPlugins);
           }
   ```
   It is redundant, because `StoragePlugins#putAll`  himself checks the 
argument nullability:

   ```java
         if (upgraded != null) {
           upgraded.putAll(locatorPlugins);
         }
   ```
   It is redundant, because `upgraded` is just initialized with a constructor 
just a few lines above and not overridden.
