Asela Illayapparachchi commented on LANG-703:
---------------------------------------------
{code:java}
StringUtils.join(new Object[]{
new Object() {
@Override
public String toString() {
return "";
}
},
new Object() {
@Override
public String toString() {
return null;
}
}
}, ',');
{code}
NPE occurs only when first Object toString method returns null
> StringUtils.join throws NPE when toString returns null for one of objects in
> collection
