[classlib][security]compatibility: exception order javax.crypto.ExemptionMechanism.getInstance(null,Provider)
-------------------------------------------------------------------------------------------------------------

         Key: HARMONY-762
         URL: http://issues.apache.org/jira/browse/HARMONY-762
     Project: Harmony
        Type: Bug

  Components: Classlib  
    Reporter: Vladimir Ivanov


The harmony method javax.crypto.ExemptionMechanism.getInstance(null,Provider) throws the NPE
while RI throws NoSuchProviderException in case when both parameters are incorrect.

=================== test.java ==========================
import javax.crypto.*;

public class test  {
  public static void main (String[] args) {  
      try {                            
            ExemptionMechanism.getInstance((String) null, "aaa");                        
                                                                                         
                                                                                         
              
      } catch (Exception e) {
          e.printStackTrace();
      }    
   }
}
