Seems fixed in version: ImageMagick 6.9.5-10 Q16 x86_64 2016-09-26 http://www.imagemagick.org

One more relevant info on OS X (MacPorts) - workaround.

After uninstall last version (ImageMagick@6.9.5-9_0+x11) and activate ImageMagick @6.9.5-8_0+x11, PDF is correctly generated.

$ sudo port uninstall ImageMagick@6.9.5-9_0+x11
---> Deactivating ImageMagick @6.9.5-9_0+x11

All of them works fine, except "fax" and "group4" (best compression for bitonal files).

$ convert ./FzwRW-1.jpg -threshold 60% -compress JPEG2000 ./out.pdf
$ convert ./FzwRW-1.jpg -threshold 60% -compress B44 ./out.pdf

Did some successful tests withing Windows ImageMagick through cygwin 64bit.

$ convert -list format | grep -i jpeg

and supplement 61 which adds JPEG-2000 encoding.

Here are the results:

$ convert -list format | grep -i jpeg
see part 5 which describes the image encoding (RLE, JPEG, JPEG-LS),
and supplement 61 which adds JPEG-2000 encoding.
J2C* JP2 rw- JPEG-2000 Code Stream Syntax (2.1.0)
J2K* JP2 rw- JPEG-2000 Code Stream Syntax (2.1.0)
JNG* PNG rw ...

It should be a 2.3MB image.

Confirm.
Just run
convert ./FzwRW-1.jpg -threshold 60% ./FzwRW-input_unprotected.pdf
and you will get normal (big) PDF.
With
convert ./FzwRW-1.jpg -threshold 60% -compress Group4 ./FzwRW-input_unprotected.pdf
you will get a black page corrupted PDF.
MacOS with MacPorts.
$ convert -version ...
