Oleg Zhurakousky commented on NIFI-1378:
----------------------------------------
Schema appears to be a required, but my main point is that I do NOT believe
it's our job to validate the correctness of AMQ URI. Only AMQ can validate it
properly and it appears to do so. Less code for us to maintain, less confusion.
