    Description

      Classlib has the API for quick accessing to fields. Since serialization performance will depend on such the accessors, the idea is to implement such the accessors on magics. Slowpath is already in classlib, uses JNI to access fields, so implementation on magics will eliminate JNI transition overhead and native-side computations.
