Sebb updated IO-223:
--------------------
Fix Version/s: 2.0
> IOUtils.copy Javadoc inconsistency (return -1 vs. throw ArithmeticException)
> ----------------------------------------------------------------------------
>
> Key: IO-223
> URL: https://issues.apache.org/jira/browse/IO-223
> Project: Commons IO
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 1.3, 1.3.1, 1.3.2, 1.4
> Reporter: Adam Michalik
> Fix For: 2.0
>
>
> The javadoc for IOUtils.copy says:
> "Large streams (over 2GB) will return a bytes copied value of -1 after the
> copy has completed since the correct number of bytes cannot be returned as an
> int."
> but then it says:
> "Throws:
> ArithmeticException - if the byte count is too large"
> This is an inconsistency since -1 is always returned if the byte count is too
> large. ArithmeticException is never actually thrown.
> See IO-84 for discussion on solving the "too large byte count" problem.
