java.lang.instrument ASSERTION FAILED after adding dependency for spring boot actuators

Question

I have a java project in intellij-idea. I am using gradle to build it. Recently I have added dependency for spring boot actuators and since then I am getting this error on startup:

*** java.lang.instrument ASSERTION FAILED ***: "!errorOutstanding" with message transform method call failed at JPLISAgent.c line: 844

My application is still running after that but I would like to get rid of this error.

I was trying to find the answer on google but I was not able to find any.

I would appreciate any help. Thank you.

Maybe not directly related to your problem, because mine had nothing to do with the Spring Boot Actuator, but maybe it might help someone else.

My problem occurred while I was testing my REST controllers. I do not provide DTOs but return my entities directly. I also have a bidirectional One-To-Many relationship between Parent and Child. The GET was producing application/json as MediaType.

@Entity
public class Parent {
    ...

    @OneToMany(mappedBy = "parent")
    private Set<Child> children;

    ...
}

@Entity
public class Child {
    ...

    @ManyToOne
    @JoinColumn(name = "PARENT_ID", referencedColumnName = "ID")
    private Parent parent;

    ...
}

If I use my entities like this and was querying e.g. for a parent by id the JSON implementation was triggering a recursion between Parent and Child, but eventually returned with a value to my test. To solve this problem I just added a @JsonIgnore to the parent field. Which in this case was sufficient for my requirements.

@Entity
public class Child {
    ...

    @ManyToOne
    @JoinColumn(name = "PARENT_ID", referencedColumnName = "ID")
    @JsonIgnore
    private Parent parent;

    ...
}
