Weird GCJ/CNI Behaviour

[Ranjit Mathew <rmathew at hotmail dot com>]

Hi,

    I was trying out something recently and came across
this problem - it flummoxes me and I would really appreciate
insights into the cause of the problem. It happens with
both 3.2 as well as 3.3 on MinGW.

Here're the two files in question:
------------------------ Foo.java ----------------------------------
 1 import java.io.File;
 2
 3 public class Foo {
 4   public static void main( String[] args) { }
 5
 6    public native void bar( String[] s, File f);
 7 // public native void bar( File f, String[] s);
 8 }
------------------------ Foo.java ----------------------------------

------------------------ snafu.cc ----------------------------------
 1 #include "Foo.h"
 2 #include <java/io/File.h>
 3
 4    void Foo::bar( jstringArray s, java::io::File* f) { }
 5 // void Foo::bar( java::io::File* f, jstringArray s) { }
------------------------ snafu.cc ----------------------------------

I then do:
    gcj -C Foo.java
    gcjh Foo
    gcj --main=Foo Foo.java snafu.cc

If defined this way, I get undefined reference errors like this:
------------------------------------------------------------------
/e/src/tmp > gcj --main=Foo Foo.java snafu.cc
D:\TEMP/cc0Aaaaa.o(.data+0x20): In function `ZN3FooC1Ev':
e:/src/tmp/Foo.java:1: undefined reference to `Foo::bar(JArray<java::lang::String*>*, java::io::File*)'
D:\TEMP/cc0Aaaaa.o(.data+0x64):e:/src/tmp/Foo.java:1: undefined reference to 
`Foo::bar(JArray<java::lang::String*>*, java::io::File*)'
------------------------------------------------------------------

which is weird, since I obviously have it defined and piping
the output of nm on snafu.o through c++filt confirms it.

However, the weirder thing is that I get *no error* if the
commented lines in each file above replace their uncommented
peers!

Why should the order make a difference?
Does it happen on other platforms as well?

Thanks in advance for your insights.

Ranjit.
