There is a problem with the JIT compiler in
JDK 1.1.6
for example on the following code

mal2@vladik2 /winfiles/Y: cat X.java
/* ========== This is the code to clean up the databas from old data ======== */
import java.util.*;

class X implements java.io.Serializable {

    public static void main(String[] args) throws Throwable {

  ResourceBundle resources=null;
       if(args.length!=3)
       {
        System.err.println("usage: CleanUpTheDataBase days_offset_start days_offset_end ConfigFile");
        System.exit(1);
       }
  System.err.println("LEN="+args.length);
      long d_start=0,d_end=0;
      try {
       d_start=new Long(args[0]).longValue();
      }catch(Exception e1)
      {
        System.err.println("Invalid date offset "+args[0]);
        System.exit(1);
      }
      try {
       d_end=new Long(args[1]).longValue();
      }catch(Exception e1)
      {
        System.err.println("Invalid date offset "+args[1]);
        System.exit(1);
      }
      
       /* read configuration */
       String stmp;
       try {
           stmp=new String(args[2]);
        System.err.println(" REDAING PROPERTIES "+args[2]);
           resources = PropertyResourceBundle.getBundle(stmp);
        System.err.println(" DONE ");
       } catch (MissingResourceException mre) {
           System.err.println("Server.properties not found");
           System.exit(1);
       }
      Object [] pagehandlers=null;

       String dataBaseAddress=null;
       String sqlDriver=null;
       String login=null,password=null;
       try {
         dataBaseAddress=resources.getString("dataBaseAddress");
       } catch(Exception e1) {
         System.err.println("No Database URL specified (dataBaseAddress)");
         System.exit(1);
       }
       try {
         sqlDriver=resources.getString("sqlDriver");
       } catch(Exception e2) {
         System.err.println("No SQL Sriver specified (sqlDriver)");
         System.exit(1);
       }
       try {
         login=resources.getString("login");
         password=resources.getString("password");
       } catch(Exception e3) {
         System.err.println("No Login or Password specified (login or password)");
         System.exit(1);
       }

      long t_curr=System.currentTimeMillis();

  System.out.println("CLEAN:: Starting cleaning");
      Hashtable handlers=new Hashtable(2000 );
        Object oph;
        int xi;

      for(xi=0;xi<pagehandlers.length;xi++)
   {
System.err.println(xi);
oph=pagehandlers[xi];
handlers.put(oph,oph);
}

 System.out.println("CLEAN:: DONE");
   }
        
}
----------------------------
mal2@vladik2 /winfiles/Y:

It prints:
mal2@vladik2 /winfiles/Y: cat txt.txt
H:\>java X 0 0 S1
LEN=3
 REDAING PROPERTIES S1
java.lang.ArrayIndexOutOfBoundsException
        at java.util.ResourceBundle.getLoader(Compiled Code)
        at X.main(Compiled Code)

H:\>java -nojit X 0 0 S1
LEN=3
 REDAING PROPERTIES S1
Server.properties not found

H:\>
mal2@vladik2 /winfiles/Y:
So it works OK with java -nojit X 0 0 S1
and does not work with java X 0 0 S1

mal2@vladik2 /winfiles/Y: cat TST.BAT
 java X 0 0 S1
 java -nojit X 0 0 S1

Here's another test case (from a web bug incident)

NT 4.0
jdk1.1.6

Here's the code
package tst;
import java.util.ResourceBundle;
import java.text.MessageFormat;

public class ResTst {
        String ERR = "ERR";

        public static void main(String argv[]) {
                ResTst c = new ResTst();
                String [] items = {
                        c.ERR
                };
                ResourceBundle rbMessages=ResourceBundle.getBundle("tst.ResTstMsgs");
                for( int x=0;x<items.length;x++) {
                        String s = rbMessages.getString(items[x]);
                        System.out.println(items[x] + " : " + s);
                }
                String s = rbMessages.getString("ERRARGS");
                String ss = MessageFormat.format(s, new Object[] { "House", "Burning"});
                System.out.println(s + " : " + ss);

        }
}

Here's the properties:
ERR=TST Error Message
ERRARGS=Your {0} is {1}


Heres the output with jit:
java.lang.ArrayIndexOutOfBoundsException
        at java.util.ResourceBundle.getLoader(Compiled Code)
        at tst.ResTst.main(Compiled Code)

Heres the output wothout jit(-nojit)
ERR : Error Message
Your {0} is {1} : Your House is Burning
