Hi,
Find attached diff of bug fix for -- StringOutOfBoundsException while trying
to connect to a URL.
Bug is found and fixed in
"/libraries/javalib/kaffe/net/www/protocol/http/HttpURLConnection.java" of
Kaffe-snap-20010819.
In brief -- I found out that testing for end of string is not done when
reading header, which could lead to StringOutOfBoundsException.
Thanks & regards,
Santosh.
