There are cases where MP stuff may clash with older apps, and we caught a couple of these cases in TomEE TCK.
For instance if a webapp is only using servlets and is exposing a servlet in the context root, because MP expose predefined REST endpoints for health, metrics, openapi, etc. the REST Service deployer is going to override the context root to be able to deploy the MP specific endpoints and the original servlet path is not going to work anymore, so you get a 404. Another case is if you already have any kind of servlet or rest endpoint with the same path of the specific MP endpoints. So the point is, there is a risk that when you upgrade to a TomEE version with MP support your older apps may clash and they will break and I believe no one would want that :) Cheers, Roberto > On 16 Jan 2019, at 17:46, David Blevins <[email protected]> wrote: > > Zooming back to the start of this thread, can you give some insight on why > anyone would want to disable MicroProfile support?
