Hi everyone

I just migrated our app to immutant and while it works great with lein run or in the repl, running the uberjar leaves me with blank responses from undertow

Also seeing ERROR: HQ214016: Failed to create netty connection when the app starts, which I’m not sure is related to undertow?

@jfntn: that error looks like it is from HornetQ. Can you gist the full log? and your project.clj?

@jfntn smells like a conflict, i.e. some dep is dragging in a different version of netty. see what lein with-profile :uberjar deps :tree says

@jcrossley3: what are you doing here?!!?

avoiding my family?

pb

I'm happy to help with that

t!

Hi @tcrawley , @jcrossley3 lein deps :tree doesn’t show any conflicts, I’ve had to add some exclusions to get there though. I also learned that this command is not bulletproof since we were unable to add alpeh to our project due to a dependency conflict with datomic around netty in fact. This issue didn’t appear in the ouput of lein and would only show up using mvn.

@jfntn: I would suspect a difference in dependencies brought in by the :dev vs :uberjar profiles, since you see different behavior with the uberjar. Try lein with-profile uberjar deps :tree and compare that to lein deps :tree (which will use the :dev profile)
