> We should upgrade to at least JDK11, or preferably current latest LTS JDK17
>  
> Plan for migration:
> *Compilation*
> JDK8 will still be used to *compile* source code (both source/target will stay `1.8`): this is required to make sure as we migrate to JDK11, we don't add dependencies on features not compatible w/ JDK8. Migrating off JDK8 in toolset, will happen at a later point, when we would stop providing any assurances about the code being able to be run on 1.8.
> *Runtime*
> JDK11 will be used to *run* the code: due to JVM b/w compatibility there should be no issues of running the code compiled for 1.8 on JDK11+, other than dependencies compatibility. For that we would make sure that all our test-suites do run against JDK11+.
