hi, Jagan,

Just a kind reminder. The current Kepler includes at least the following 
three cog-related jars in $KEPLER/lib/jar:


When you add in the new cog-4.1.3.jar, please make sure it does not 
conflict with those "old" jar files. Some actors uses those old jar files. 
You may not get any problem when you compile those actors with the new 
jar, but running those actors may cause errors. Just be very careful not 
breaking the old actors/workflows when you check in new jars.

Actually there are some "old" jar files existing in Kepler that needed to 
be updated. Updating those jars without breaking the old actors/workflows 
is still an interesting topic in Kepler group. Anybody has any
