This affects not only versions 2.0.*, but also 1.900.*.  The problem remains unfixed in the currently latest upstream version 2.0.16.

This flaw exists in the code for writing image into the RAS (Sun Raster) format.  It does not affect the most typical uses of Jasper library to read JPEG2000 images.
