Exceptions priority in InputStream.read(byte[], int, int)

[Martin Buchholz]

When there is a choice of exceptions to be thrown, it's not usually
specified which one wins.
Usually there's a natural order of operations that cause e.g. argument
checking to happen first.
Sometimes a code change can cause a different exception to be thrown,
and that occasionally causes compatibility trouble.
