> IOUtils.toByteArray throws inconsistent exceptions
> --------------------------------------------------
>
> Key: IO-696
> URL: https://issues.apache.org/jira/browse/IO-696
> Project: Commons IO
> Issue Type: Bug
> Reporter: ackelcn
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> The code of this method is as follows:
> {code:java}
> public static byte[] toByteArray(final InputStream input, final int size)
> throws IOException {
> if (size < 0) {
> throw new IllegalArgumentException("Size must be equal or greater
> than zero: " + size);
> } if (size == 0) {
> return new byte[0];
> } final byte[] data = new byte[size];
> int offset = 0;
> int read; while (offset < size && (read = input.read(data,
> offset, size - offset)) != EOF) {
> offset += read;
> }
> if (offset != size) {
> throw new IOException("Unexpected read size. current: " + offset
> + ", expected: " + size);
> } return data;
> }
> {code}
> When size is below zero, it throws IllegalArgumentException, but when size is
> not equal to offset, it throws IOException. It is somewhat confusing. It
> shall throw IOException in both cases, in that both cases check legal sizes.
