      Description

      FULL PRODUCT VERSION :
      Java(TM) SE Runtime Environment (build 1.7.0_01-b08)
      Java HotSpot(TM) 64-Bit Server VM (build 21.1-b02, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows [Version 6.1.7601]

      A DESCRIPTION OF THE PROBLEM :
      when I want to chech string variables in switch statement like that:

       public void doJob( String foo )
       {
            switch (methodName)
            {
          case ( " A " ): // wrong string comparison, decleration error (*)
          {
          doAJob();
          }break;
          case " B " : // string comparison right
                      {
               doBJob();
          } break;
          default :
           System.err.println( " No such param " );
      }
       }

      (*) At line 7: there is a syntax error but javac can't understand it. It says " An exception has occurred in the compiler (1.7.0_01) " . But I tried the code in java version " 1.5.0_05 " . It can see the decleration error.


      REGRESSION. Last worked in version 5.0
