AppMap Recording Failure in Spring Boot Applications

Hello, at our organization, a team installed AppMap as part of an initiative to evaluate GenAI developer assistance tools for licensing. However, we are consistently encountering an issue while running our Java Spring Boot application with AppMap. We have tried exploring the AppMap documentation and other resources, but we have been unable to resolve the error.

We would appreciate any support you can provide, as we are interested in further exploring AppMap and recommending it for an organization-level license if it works as documented.

Spring Boot : v2.7.13 and Spring : v5.3.28 and Java : 17.0.8

The error log for the Spring Boot application is as follows:
