java.text.ChoiceFormat.format(long, StringBuffer, FormatStatus) causes
StackOverflowError. To reproduce, exec the following test program.

import java.text.*;

public class bug1{
    public static void main(String[] args){
//
        double[] limit = {0.0,1.0,2.0};
        Object[] format = {"0.0<=Limit<1.0",
                            "1.0<=Limit<2.0",
                            "2.0<=Limit"};
        ChoiceFormat cf = new ChoiceFormat(limit,format);
        FormatStatus status = new FormatStatus();
        StringBuffer toappendTo = new StringBuffer("");
//
// main
//
// System.out.println(cf.format((double)1.0,toappendTo,status)); // OK
        System.out.println(cf.format((long )1.0,toappendTo,status)); // NG
    }
}

Exec result:
