Subject [jira] [Commented] (LANG-701) StringUtils join with var args
Date Fri, 09 Nov 2012 07:58:12 GMT

    [ https://issues.apache.org/jira/browse/LANG-701?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13493807#comment-13493807
] 

Joerg Schaible commented on LANG-701:
-------------------------------------

bq. the input array should be of Object type, not String, which will cause a stack overflow
with the proposed APIs because the boolean arg will go into the Object array. This would not
happen with a String array but it would greatly reduce the functionality.
The input array could be at least CharSequence then.

> I missed the functionality of joining strings with the space separator in one line. BTW,
why space ' ' not a constant field anywhere?
