The following code

import java.text.MessageFormat;

public class Test {
    public static void main(String args[]) {
        MessageFormat messageformat = new MessageFormat("test Message = {0}");

        Object aobj[] = new Object[1];
        aobj[0] = new String("a jolly string");
        System.out.println(messageformat.format((Object) aobj));
    }
}

produces different results when compiled with gcj than it
does if run in either Sun's (1.2) or IBM's (1.3) JDK

$ javac Test.java
$ java Test 
test Message a jolly string
$ gcj Test.java --main=Test -o test
$ ./test
test Message [Ljava.lang.Object;@807dfc0

>How-To-Repeat:

>Fix:
Presumably the Sun JDK has a(n undocumented) test in the
java.text.format(Object obj) method to see if the object
is really an array and behave differently if so.
