Amareshwari Sriramadasu commented on LENS-139:
----------------------------------------------
Remove resources gets more complicated with db resources added. Should we
remove the functionality of "removing resources"? I don't see much usecases
requiring this. If there is any, user can always create new session and add
fresh jars.
Thoughts?
