      Description



      Name: laC46010 Date: 06/25/99



      New javac (jdk1.3-H) fails to pass the following JCK-122 test:

      lang/STMT/stmt035/stmt03505/stmt03505.html

      Note that this is regression of bug#4157779 fixed in jdk1.2fcs.
      and oldjavac also passes the test successfully.

      See reduced test source and compiler output below.

      ------------------------------------------------------------------------------
      public class stmt03505 {

         public static void main(String argv[]) {
            System.exit(run() + 95/*STATUS_TEMP*/);
         }
         public static int run() {

            try {
                switch ( 0 ) {
                    case 0:
                    case 1 - (1<<31):
                    case (1<<31):
                }
                return 0;/*STATUS_PASSED*/
            } catch( OutOfMemoryError e) {
                return 2;/*STATUS_FAILED*/
            }
         }
      }
