I just came across the same situation. I quick experiment showed that interpolation doesn't work with the fast coverage render path. It works with the normal one though.
With the fast coverage render path, bilinear produces strange colors, and bicubic gives an ArrayIndexOutOfBoundsException: 257. The 257 is significative because the coverage is a single band 16-bit color indexed image with a pallete of 257 values. I can create a separate jira if not related though.
