 The meaning of each possible option is as follows:
   'all' - is the preferred option, and it enables all other behaviors.
 
   'none' - forcefully disables all enabled options. This can be used only on the command line to override choices taken by inaccessible parts of the build process.

   'complete-reflection-types' - reflective registration of a type, via metadata files or the Feature API, always includes all type metadata. Now, all registered types behave the same as types defined in 'reachability-metadata.json'.
 
   'run-time-initialize-security-providers' - shifts away from build-time initialization for 'java.security.Provider'.
