Tree view

All,
I have noticed a strange behavior in jdbc. Consider the following code:

/*
          CREATE TABLE public.testtbl (
            a integer,
            b character varying(50));
         */
        Class.forName("org.postgresql.Driver");
        Connection con = DriverManager.getConnection("jdbc:postgresql://localhost:5432/postgres?loglevel=0","postgres","postgres");

        PreparedStatement stmt = con.prepareStatement("insert into testtbl values(?,?)");

        for (int i=0; i< 400;i++) {
            stmt.setInt(1, 110);
            if (i==0)
                stmt.setString(2, "Hello\0 Mr.X");
            else
                stmt.setString(2, "Hello Mr.X");
            stmt.addBatch();
        }

        try{
            stmt.executeBatch();
        } catch(Exception exp){
            stmt.clearBatch();
            exp.printStackTrace();
        }

        for (int i=0; i< 400;i++) {
            stmt.setInt(1, 10);
            stmt.setString(2, "Hello Mr.X");
            stmt.addBatch();
        }
        stmt.executeBatch();

When I execute this code, I get Two errors:

(1):
java.lang.IllegalArgumentException: org.postgresql.util.PSQLException: Zero bytes may not occur in string parameters.
        at org.postgresql.core.v3.SimpleParameterList.toString(SimpleParameterList.java:163)

        at org.postgresql.jdbc2.AbstractJdbc2Statement.executeBatch(AbstractJdbc2Statement.java:2727)
        at Main.main(Main.java:28)

This error is fine because I am adding an invalid character. Here is 2nd error:
(2)
java.lang.IndexOutOfBoundsException: Index: 145, Size: 145
        at java.util.ArrayList.RangeCheck(ArrayList.java:546)
        at java.util.ArrayList.get(ArrayList.java:321)

        at org.postgresql.jdbc2.AbstractJdbc2Statement.executeBatch(AbstractJdbc2Statement.java:2727)
        at Main.main(Main.java:39)

If I remove the first error, the second error is automatically removed. To me, it seems that this is some after effect of the first error. What is wrong here?
