This is the environment used:

Spring Boot 2.4.6 Maven 3.8.6 Java SDK 1.8 Library version: 0.2.13

@oyvindhorneland @lukashinsch Please help in rectifying the issue or atleast where I am going wrong.

[lukashinsch]

Unfortunately, this (old) project uses spring boot 1.x, and in 2.x there were breaking changes regarding the actuator infrastructure. Sorry to disappoint you.

[shortthirdman]

Any intentions on developing that for Spring Boot 2.x.x? @lukashinsch
