Subject [jira] Created: (LANG-568) @SuppressWarnings("unchecked") is used too generally

@SuppressWarnings("unchecked") is used too generally
----------------------------------------------------

                 Key: LANG-568
                 URL: https://issues.apache.org/jira/browse/LANG-568
             Project: Commons Lang
          Issue Type: Bug
          Components: General
            Reporter: Sebb
             Fix For: 3.0


@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:

ArrayUtils.<String>add((String[])null, null);

generates a ClassCastException, which should not happen if the warning is OK to ignore.
