      Description

      When allocating a 200 MB tab, a OOM is thrown. Here is a code which lead to a OOM :

      package lip6.jikesrvm.bench;

      public class Test
      {
      public static final int NB_ELEM = 200 * 1024 * 1024 / 4;
      private static int[] tab;

      public static void main(String args[])

      { tab = new int[NB_ELEM]; }

      };

      The program is run with rvm -cp barrier/bin -Xms1G -Xmx1.5G -X:processors=all lip6.jikesrvm.bench.Test

      This perfectly run with sun JVM or with NB_ELEM set at 20 * 1024 * 1024
