The JPEG plug-in handles images with low bit depths incorrectly. For example,
for a BufferedImage of type TYPE_USHORT_565_RGB a pixel values of (31, 63, 31)
should produce white, not olive green. The same problem occurs when reading
into a user-supplied BufferedImage as well as when encoding such an image.
The existing regression test in test/javax/imageio/BitDepth.java
may be used to demonstrate the encoding problem.
