When the service starts, it suddenly stops, which is suspected to be a deadlock. How to use jstack or VisualVm to locate?

problem description

every time a service is started on Mac, it stops during startup (normally other services and more daemon threads will continue to be started), but the process is still running. Booting is normal on Windows systems.

the environmental background of the problems and what methods you have tried

it is initially suspected that it is caused by thread deadlock. Try using jstack to see if it is deadlock, as shown below.

what result do you expect? What is the error message actually seen?

I hope that students who are familiar with me will give us some advice as to whether it is caused by deadlock and how to continue to locate it.

Deadlock java
Apr.22,2021

start parameter plus-Djava.awt.headless=true try

No deadlock occurs. If a deadlock occurs, it will clearly prompt (Found one Java-level deadlock), to look at the thread and should be stuck on jar loading. This can also explain why the phenomenon is different in different development environments
