(Spring Boot 2.7.18) After running the application, something filling in the Eden Space

Question

You can see the executed application code in https://github.com/JadeKim042386/AccountService.

[Environment]

• Mac M1
• JDK 17 / G1 GC

[VM Options]

• -Dcom.sun.management.jmxremote.port=1099 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Xms1024m -Xmx1024m

I just ran this application and checked GC with VisualVM(with VisualGC plugin).

I want to know what keeps filling in Eden Space. Is there any way I can figure it out?
