incorrect JPX foreground image rendering

Description
Page 6 of the attached PDF is rendered incorrectly with the Xpdf-derived JPX decoder in poppler. When poppler is compiled with OpenJPEG support, the image renders correctly. Would suggest deprecating the existing JPX decoder in poppler and recommending that all distributions use OpenJPEG.
Page 6 is a three-image composite of a reduced-resolution JPEG background image, reduced-resolution JPEG2000 foreground image, and a full-resolution JBIG2 image mask. The poppler JPX decoder causes white ghosting in the upper-right corner of the text. (The PDF was originally generated with ABBYY FineReader 9 in MRC mode)
