    Description


      The following test fails on Linux and Windows while executing against HotSpot Server VM in -Xcomp mode.
      ------------ test.java -----------
      public class test {
        public static void main (String[] args) {
           String[] modulos={"1" , "2"};
           for (int md=0; md<modulos.length; md++) {
             BigInteger modulo = new BigInteger(modulos[md]);
             System.out.println(modulo);
             new BigInteger("10").mod(modulo);
           }
        }
      }
      ----------------------------------

      Below is output from the test execution:
      -----------------------------------------------------
      %java -server -Xcomp test
      1
      2
      Exception in thread "main" java.lang.ArithmeticException: / by zero
              <<no stack trace available>>
      %java -server test
      1

      %java -client -Xcomp test

      %java -client test

      %
      -----------------------------------------------------

      The JDK version is:
      java version "1.3.1beta"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1beta-b08)
      Java HotSpot(TM) Server VM (build 1.3.1beta-b08, compiled mode)

      The test passes in -Xmixed and in -Xint modes against JDK 1.3.1 Server VM; as well as the test passes in all execution modes against the Client VM.
      The test passes against JDK 1.3.1-b07 both Client and Server VMs in all execution modes.

      The following JCK1.3 api tests fail due to this bug against JDK1.3.1beta-b08 HS Server VM in -Xcomp mode:
