I've now checked this with native and GNU iconv: feff.utf-8 is the input
sequence from iconv_init:

> od -x feff.utf-8
0000000 bbef 0abf

At first everything seemed to work with both tools, except that I need
byte swapping with native iconv, but not with GNU iconv:

> /usr/bin/iconv -f UTF-8 -t UCS-2 < feff.utf-8 | od -x
0000000 feff 000a
> /vol/gnu/bin/iconv -f UTF-8 -t UCS-2 < feff.utf-8 | od -x
0000000 fffe 0a00

But when I removed the newline from the input file, results differ:

> od -x feff.utf-8-nonl 
0000000 bbef 00bf

> /usr/bin/iconv -f UTF-8 -t UCS-2 < feff.utf-8-nonl | od -x
0000000 feff feff
> /vol/gnu/bin/iconv -f UTF-8 -t UCS-2 < feff.utf-8-nonl | od -x
0000000 fffe

As result, I've simply added a padding NUL byte to the input sequence.
This let the iconv succeed and my arraycopy testcase and both md5test
and shatest pass.

I'm running a full rebuild and check of libjava for good measure.
