Review comment:
       Yes, and since isEmpty and isAsync are only used once I ended up 
changing it to this:
   ```
       synchronized (commandQueue) {
         if (!commandQueue.isEmpty()) {
           commandQueue.offer(command);
           return;
         }
         if (command.getCommandType().isAsync()) {
           commandQueue.offer(command);
           startAsyncCommandExecution(command);
           return;
         }
         executeCommand(command);
       }
   ```
