Evaluation

It happens when the VIS or VIS2 version of libclib_jiio.so is used.
The C version libclib_jiio.so doesn't seem to cause any VM crash, and
the ReadRenderedTest test can show the correct part of the image.

Actually the VIS versions do not crash the VM every time with the
corrupted image. The problem was that the decoder didn't check for
the situation of missing EOI marker. When it happened, the decoder
used garbage data in the buffer to do decoding which may or may not
run out of the buffer and cause athe VM to crash depending what were
in the buffer. The docoder ought to be updated to handle this
situation gracefully.
