cannot opj_decompress file compressed with opj_compress

[GoogleCodeExporter]

opj_compress -i img.png -o img.jp2
    [INFO] tile number 1 / 1
    Generated outfile img.jp2

opj_decompress -i img.jp2 -o img.bmp
    !! Unrecognized format for infile: img.jp2 [accept only *.j2k, *.jp2, *.jpc or *.jpt] !!

I have compiled openjpeg-2.0.0 from sources on linux 2.6.24 debian 4.0

The img.jp2 header is this :
00 00 00 0C 6A 50 20 20 FF 4F FF 51 00 2F 00 00 

I understand it should be
JP2_RFC3745_MAGIC  00 00 00 0c 6a 50 20 20 0d 0a 87 0a 
or      JP2_MAGIC  0d 0a 87 0a

Hum, neat example indeed:
