----------------------------------
Do you have any particular examples/test cases in mind where there are
problems, or is this theoretical?
> EndianUtils.readSwappedUnsignedInteger() may return a negative number

> Key: IO-117
> URL: https://issues.apache.org/jira/browse/IO-117
> Project: Commons IO
> Issue Type: Bug
> Affects Versions: 1.3.1
> Reporter: Hiroshi Ikeda
>
> Methods about reading unsigned-integer in class EndianUtils may return a
> negative number, due to casting int to long.
> Calculations with operator & etc. are under integer in these methods so its
> results are integer,
> then implicit casting the results to long keeps its positive/negative sign.
