      Description



      Name: vtR10009 Date: 06/07/2002


      Implementation of javax.print.PrintServiceLookup abstract class cannot
      locate all print services if a large number of services (~900 in SWAN)
      are available in the system.

      This bug causes failure of JCK tests:
      api/javax_print/CancelablePrintJob/index.html#Cancel
      api/javax_print/DocPrintJob/index.html#AttributeListener
      api/javax_print/DocPrintJob/index.html#Get
      api/javax_print/DocPrintJob/index.html#JobListener
      api/javax_print/PrintService/index.html#hashCode

      The following test hangs running on JDK 1.4.1-beta-b14:
      ------------------------------- test.java --------------------------------
      import javax.print.*;
      import javax.print.attribute.*;
      import javax.print.event.*;

      public class test{
          public static void main(String args[]) {
              PrintService[] pservices;
              
              pservices = PrintServiceLookup.lookupPrintServices(null, null);

              if (pservices.length == 0){
                  System.out.println("OKAY: no print services found");
                  System.exit(0);
              }
              System.out.println("Number of services: " + pservices.length);
              for (int i = 0; i < pservices.length; i++) {
                  System.out.println(" Pservice: " + pservices[i] + " "
                          + pservices[i].getName());
              }

              System.exit(0);
          }
      }
