[ https://issues.apache.org/jira/browse/NET-276?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13026112#comment-13026112 ]
BattousaiX commented on NET-276:
--------------------------------
I have tried your code, but there is an error with the following line.
result._setNewsgroup(tokenizer.nextToken());
_setNewsgroup method is not visible.
Were any other modifications made?

> My hypothesis is that NNTP cannot parse the response, because one of the numbers exceeds the Integer range.
> Locally I have applied the following quick fix to get it to work:
> public class NNTPClient extends NNTP {
