Missing real name (?) causes StringIndexOutOfBoundsException during processing of 352 server response #151

Closed GoogleCodeExporter closed 9 years ago

I got this error during a list of 352 server responses.

I'm not totally sure, but it seems to be related to the case where no real name 
is given. In that case the output gets trimmed and consequently there is never 
a trailing space after the value for the number of hops. I guess this results 
in an index of -1 and that's of course not valid for a substring operation. 
(From quickly looking at the code, it seems that the Tokenizer at 
InputParser.java:284 automatically trims.)

I did a temporary fix myself (attached) that seems to do the trick, so it might 
be useful. 

The stack trace that gets produced:

[Thread-24] ERROR org.pircbotx.PircBotX - Exception encountered when parsing 
line

Its surprising that I've never seen a user with a missing full name before when 
testing. Fixed in Revision e6f2fb76479b with a unit test.
