弹簧执行器关闭端点无法停止Java进程

Question

I want to shutdown my spring boot application (spring boot v2) with the actuator endpoint. I have successfully enabled the shutdown endpoint with spring-actuator (see application.yml). I can also call the endpoint and spring shuts down the application context (see logs and curl command).

But somehow the java process is not getting killed. I also tried to pack my application into a docker container to ensure it is not a local installaton problem with java. But no success - java process still running.

The application is started in development mode with H2 database and Spring-Data-Jest for elasticsearch.

Update: I have set up a production environment with mysql+elasticsearch running in docker. I started the application with production profile but still have the same problem. So I guess it is not a problem with local h2 and local in memory jest elasticsearch instance.

Any help would be appreciated - Thanks
