The problem is in the j2d_glReadPixels() in OGLBlitLoop.c:
// we must read one scanline at a time because there is no way
// to read starting at the top-left corner of the source region
while (height > 0) {
j2d_glPixelStorei(GL_PACK_SKIP_ROWS, dsty);
j2d_glReadPixels(srcx, srcy, width, 1,
pf.format, pf.type, pDst);
srcy--;
dsty++;
height--;
}
// we must read one scanline at a time because there is no way

while (height > 0) {

j2d_glReadPixels(srcx, srcy, width, 1,
