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.
