The java.text.SimpleDateFormat.SimpleDateFormat(String pattern,
DateFormatSymbols symbols) constructor should clone second parameter
using setDateFormatSymbols() method not just store the reference.
(see source code for SimpleDateFormat.setDateFormatSymbols() method:

    public void setDateFormatSymbols(DateFormatSymbols newFormatSymbols)
    {
        this.formatData = (DateFormatSymbols)newFormatSymbols.clone();
    }

)
   
 
Here is the test demonstrating the bug:

-----------------TestDF.java------------------------
import java.text.*;
import java.util.Date;
public class TestDF {
    public static void main (String args[]){
        DateFormatSymbols symbols = new DateFormatSymbols();
        SimpleDateFormat df = new SimpleDateFormat("E hh:mm", symbols);
        System.out.println(df.toLocalizedPattern());
        symbols.setLocalPatternChars("abcdefghijklmonpqr"); // change value of field
        System.out.println(df.toLocalizedPattern());

    }
}
---------Output from the test---------------------
E hh:mm
j pp:gg
--------------------------------------------------
