We want to integrate Azure Service bus Java SDk in a legacy project that has JDK 8. The project compiles fine, but spits out the following run time error:
'com/azure/spring/cloud/autoconfigure/implementation/context/AzureGlobalConfigurationEnvironmentPostProcessor has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0'
I understand that upgrading the JDK version is the recommended approach but we don't have the permission to upgrade the JDK of this legacy project. Also when I tried upgrading locally, there were tons of compiation issues.
Alternatively I've tried looking for JDK 8 compatible maven dependency versions of azure dependencies in the pom.
I have created an independent project to test this bit, it worked fine when pointed to JDK 17 but as soon as it's downgraded to JDK 8 it throws the same error.
The Azure Java SDK documentation says it supports jdk 8 onwards, but it doesn't seem to work.
