javax.management.InstanceNotFoundException: org.springframework.boot:type=Admin,name=SpringApplication

I had the same issue with IDEA IntelliJ. The problem was IntelliJ’s default server configurations. You just need to remove the ‘Enable launch optimization’ and ‘Enable JMX agent’ checkboxes, then it works!

Steps:

• Edit Configurations
• choose your project
• remove the ‘Enable launch optimization’ and ‘Enable JMX agent’ checkboxes
