quarkus: Unable to shutdown after bootstrap errors

Running in “JVM mode” the demo rest-http-crud at

• https://github.com/protean-project/rest-http-crud/tree/master/shamrock

This demo requires PostgreSQL to run. If you start it w/o the RDBMS being up, then the demo boots by printing appropriate exceptions about not being able to connect to the database - but then doesn’t respond to CTRL+C signals (nor kill -3), requiring a kill -9 to stop the demo.

If instead the RDBMS is available, then CTRL+C works as expected so I assume this relates with order of setup.

Let’s make sure the signal handlers are registered consistently as very first thing?
