the gnu classpath libraries cannot handle %f in format strings:

$ cat test.java
public class test {

public static void main (String[] args) {
System.out.printf("%09.3f%n",3.1415926535);
}

}
$ cat test2.java
public class test2 {

public static void main (String[] args) {
System.out.printf("%9.3f%n",3.1415926535);
}

}
$ gcj -C -g -O test.java
$ gcj -C -g -O test2.java
