A bug report from James Im:
---- MESSAGE BEGINS ----
I need your help to determine if I have found a bug or not.
I use a slightly modified version of TextLineDecoder and I got an error
in decodeNormal() at line 272 (the line number correspond to the version
on the trunk):
in.limit( in.limit() - matchCount + oldMatchCount );
After investigating a bit I found that I was trying to set the limit to
8193 which was greater than the capacity (8192). Thus the error.
I've investigated some more and I saw that it happened when the
matchCount passed to decodeNormal() was 1 instead of 0.
I've investigated some more and I think that oldMatchCount should be
reset to zero when you have found a match.
Thus, after line 261 I have added:
oldMatchCount=0;
After I did this change the problem was solved. The problem did not
occurred 100% of the time on my server and thus I have no specific test
case to reproduce the problem.
As it is hard to analyze buffer, position, limit, remaining and capacity
in loops and I therefore ask you to do a mental effort to verify if I
am right or wrong.
