      Description



      Name: akC57697 Date: 07/07/97



      The java.io.ByteArrayOutputStream.write([],int,int) causes
      segmentation violation with parameters out of bounds instead of
      IndexOutOfBoundsException ( or OutOfMemoryException)


      --------------------------- Test.java --------------------
      import java.io.*;
      public class Test {

        public static void main(String[] args) {
                   
       ByteArrayOutputStream y1;
       byte array1[]={49,50,51,52,53};
       
         y1 = new ByteArrayOutputStream(100);
         
        for (int i=0;i<3;i++) {
       
         try {
          y1.write(array1,0,Integer.MAX_VALUE-i); // It is works without "-i"
         } catch (IndexOutOfBoundsException e)
         { System.out.println("OKAY");
         }
          catch (Throwable e)
         { System.out.println("Unexpected "+e);
         }
         y1.reset();
        }
       }
      }
