Thanks for the report, but those stats from JConsole are rather meaningless on their own. For example, while the current heap size with mvn spring-boot:run is 164MB whereas it's java -jar it is 648MB that doesn't tell us anything about how much memory is actually being used as we don't know how many of the objects on the heap are reachable. Garbage collection may have run recently in the java -jar case, freeing up a large amount of heap.

I've you'd like us to spend some time investigating the problem, please provide a small sample that we can run with mvn spring-boot:run and java -jar and observe the different memory usage.
