Subject [jira] Commented: (LANG-568) @SuppressWarnings("unchecked") is used too generally
Date Fri, 18 Dec 2009 19:04:19 GMT

Sebb commented on LANG-568:

Log:
LANG-568 - @SuppressWarnings("unchecked") is used too generally

I think all the warnings that can be safely suppressed have now been suppressed (and documented).

There are two warnings that remain cannot be suppressed safely; see LANG-571

> @SuppressWarnings("unchecked") is used in several places on entire methods.
> Mostly there is no documentation as to why it is safe to ignore the warnings.
> Seems to me the annotation should be used as close as possible to the site of the warning,
and the reason should be documented, so it can be revisited if there is a code change later.
> In fact, at least one of the warnings is NOT safe to ignore:
> String[] s = ArrayUtils.add((String[])null, null);
> generates a ClassCastException, which should not happen if the warning is OK to ignore.
