Hi Ruwan,

I think we already had this topic in April. ;-) At that time we identified qpid and mina,
if I'm not wrong. Mina was only used by Quickfix/J...

But here a mail I pulled of my mail archive:

This JAR only takes 9 KB. I would just leave it in the distribution.
The advantage is that whenever a user adds a library that uses the
SLF4J framework, logging will correctly work out of the box without
the need for the user to understand the relationship between log4j,
SLF4J and commons-logging.

I am completely OK with keeping this, but not QuickFixJ and other related dependencies, because
FIX is a domain specific transport which wont be required for many users.

Subject: SLF4J dependency??

Does any body know why we have slf4j libraries on the lib directory of the synapse distribution?
That was the reason for the JDK1.5 failure of the build :-(, I just want to make sure there
is no code using slf4j directly before getting rid of them :-)
