Here is the test scenario:
 final static String STR_SCHEMA = "m1:map(string),m2:map(map(int))";
  //final static String STR_STORAGE = "[m1#{a}];[m2#{x|y}]; [m1#{b}, 
m2#{z}];[m1]";
 final static String STR_STORAGE = "[m1#{a}, m2#{x}];[m2#{x|y}]; [m1#{b}, 
m2#{z}];[m1,m2]";

projection: String projection2 = new String("m1#{b}, m2#{x|z}");
User got null pointer exception on reading m1#{b}.

Yan, please refer to the test class:
