Sebb created MATH-793:
-------------------------
Summary: OrderedTuple#hashCode() uses casting instead of boxing
Key: MATH-793
URL: https://issues.apache.org/jira/browse/MATH-793
Project: Commons Math
Issue Type: Bug
Environment: OrderedTuple#hashCode() is as follows:
{code}
public int hashCode() {
return Arrays.hashCode(components) ^
((Integer) offset).hashCode() ^
((Integer) lsb).hashCode() ^
((Boolean) posInf).hashCode() ^
((Boolean) negInf).hashCode() ^
((Boolean) nan).hashCode();
}
{code}
This is not the correct way to convert primitives to their object equivalents.
((Integer) x).hashCode() == x
Boolean#hashCode() is defined as
value ? 1231 : 1237
Note that this error won't be found unless the compiler emits warnings for
boxing.
