Description

running the following code:

client.connect("news.icm.edu.pl");
NewsgroupInfo[] grps = client.listNewsgroups();

results MalformedServerReplyException (alt.atheism 2147485259 2147483647 y)

it's because in function NNTPClient.__parseNewsgroupListEntry():

last = tokenizer.nextToken();
first = tokenizer.nextToken();
permission = tokenizer.nextToken();

try

{ lastNum = Integer.parseInt(last); firstNum = Integer.parseInt(first); result._setFirstArticle(firstNum); result._setLastArticle(lastNum); if((firstNum == 0) && (lastNum == 0)) result._setArticleCount(0); else result._setArticleCount(lastNum - firstNum + 1); }

catch (NumberFormatException e)

{ return null; }

lastNum and firstNum are Integer (too small for received values)
