IteratorUtils.getIterator(Object obj) performs redundant null check
-------------------------------------------------------------------
Key: COLLECTIONS-319
URL: https://issues.apache.org/jira/browse/COLLECTIONS-319
Project: Commons Collections
Issue Type: Bug
Components: Collection
Reporter: Sebb
Priority: Minor
IteratorUtils.getIterator(Object obj) performs redundant null check:
{code}
if (obj == null) {
return emptyIterator();
...
} else if (obj != null && obj.getClass().isArray()) {
return new ArrayIterator(obj);
{code}
obj cannot be null at that point, so the check can be removed.
[This will also prevent a false positive in Eclipse which later says tha obj
may be null]
