**To Reproduce**
Steps to reproduce the behavior:

***Code Snippet***
Add the code snippet that causes the issue.

**Expected behavior**
A clear and concise description of what you expected to happen.

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Setup (please complete the following information):**
 - OS: [e.g. iOS]
 - IDE: [e.g. IntelliJ]
 - Library/Libraries: [e.g. com.azure:azure-core:1.16.0 (groupId:artifactId:version)]
 - Java version: [e.g. 8] 
 - App Server/Environment: [e.g. Tomcat, WildFly, Azure Function, Apache Spark, Databricks, IDE plugin or anything special]
 - Frameworks: [e.g. Spring Boot, Micronaut, Quarkus, etc] 

If you suspect a dependency version mismatch (e.g. you see `NoClassDefFoundError`, `NoSuchMethodError` or similar), please check out [Troubleshoot dependency version conflict article](https://aka.ms/azsdk/java/dependency/troubleshoot) first. If it doesn't provide solution for the problem, please provide:
- verbose dependency tree (`mvn dependency:tree -Dverbose`)
- exception message, full stack trace, and any available logs

**Additional context**
When checked the dependency hierarchy found both the libraries were bringing 2.13.2.2 of jackson data bind

Thanks for reporting this @MohakWadhwani.

This is interesting as 1.23.1 included this change to fix . being used for a inner class instead of the proper $. Could you ensure that azure-core 1.23.1 is explicitly included using a direct dependency. If the error continues happening after that would you mind trying azure-core 1.24.1 as it included changes to reflective access to reduce errors.

This is the correct handling and just an informational message. The MethodHandle being used for Jackson 2.12 doesn’t exist in Jackson 2.11
