With Jigsaw then the conflict will be caught when you attempt to 
install/configure a module with an entry point and that module 
ultimately requires more than one version of a module. Such a scenario 
is considered a "bug", possibly caused by overly restrictive version 
constraints. The one scenario where it may make sense is the container 
case, say a test harness or a web container that requires one version of 
a module and the test or application running in the container requires a 
different version. This isn't implemented in Jigsaw (not yet anyway) but 
is a scenario that is called out in the requirements document [1].
