Review usage of LinkedHashMap, synchronized blocks, exception handling in clusterapi in the repo

[muralibasani]

What is currently missing?

Usage of LinkedHashMap in connector calls can be replaced with HashMap ? Review usage of synchronized Exception handling in clusterapi

How could this be improved?

Usage of LinkedHashMap in connector calls can be replaced with HashMap ? Review usage of synchronized, verify if only one instance of jvm is allowed to run Exception handling in clusterapi for controllers with better try/catch or global exception handler

Is this a feature you would work on yourself?

• [X] I plan to open a pull request for this feature

Regarding exception handling, maybe it makes sense to consider the following as well:

• Avoid throwing raw exceptions
• Use "Problem Details" RFC 7807 (https://www.rfc-editor.org/rfc/rfc7807) [https://github.com/spring-projects/spring-boot/issues/32634]. Expected release date of Spring 3.0.0 is November 24, 2022
