[Joe Darcy]

Hello,

Please review this change to suppress a fall-through warning recently 
sync'ed into ASM:

      void set(final int type, final String strVal1, final String strVal2,
              final String strVal3) {
          this.type = type;


The switch statement is

         switch (type) {
         case ClassWriter.CLASS:
             this.intVal = 0;     // intVal of a class must be zero, see 
visitInnerClass
         case ClassWriter.UTF8:
         case ClassWriter.STR:
         case ClassWriter.MTYPE:
         case ClassWriter.TYPE_NORMAL:
             hashCode = 0x7FFFFFFF & (type + strVal1.hashCode());
             return;
         case ClassWriter.NAME_TYPE: {
             hashCode = 0x7FFFFFFF & (type + strVal1.hashCode()
                     * strVal2.hashCode());
             return;
         }
         // ClassWriter.FIELD:
         // ClassWriter.METH:
         // ClassWritehr.IMETH:
         // ClassWriter.HANDLE_BASE + 1..9
         default:
             hashCode = 0x7FFFFFFF & (type + strVal1.hashCode()
                     * strVal2.hashCode() * strVal3.hashCode());
         }
     }
