Do you have JP2 or JPX using the Jpeg-2000 library? Your input image may be using that format which is incompatible with the older JPEG format.

PS I have JPX but...
A zero sized rose.jpx file was created.

however jp2 works prefectly! Whats the difference between these two formats, as both are listed as JPEG-2000

Somebody have solution for this? I have the same problem. I tried to reinstall Jasper(1.900.1), JPEG2000(v8), ImageMagick(6.5.0-10), GhostScript(8.70) but no result.

JPX format is important for pdf convert to jpeg images after command:
convert -colorspace RGB -density 130 -limit memory 1mb -limit map 1mb '.$uploadfile.' '.str_replace('.pdf','.jpeg',$uploadfile).' 2>&1'

but return error:
jasper (code 0) error: cannot decode code stream unable to decode JPX image data. **** Warning: File has insufficient data for an image. ****
This file had errors that were repaired or ignored. **** The file was produced by: **** >>>> Adobe PDF Library 9.0 <<<<
