**i have update camel-core2.25.4 to camel-core3.2.0 version and im getting error while running app **
In our current project we using Java 8, Spring boot 2.7.12 with Apache Camel 2.25.4 Team is planning to upgrade camel to 3.2.X because it has the support for java 8. I saw the camel documentation which states that java 8 support will be discarded from 3.4.X version onward but struggle to find out compatible version of spring boot version required to use with camel 3.4.X Do i need to upgrade the spring boot version? and if yes which version would be it or where i can find out.
