Prototype the snapshot model with CDS+AOT

    Details

      Description

      Currently both CDS and AOT assumes that the VM starts in an empty state, and classes are loaded incrementally as they are referenced by the app. This results in a large number of run-time checks to ensure that the classes loaded by the app are the same as those used when the CDS/AOT caches were created. These checks slows down start-up, and also make the caches larger than usual.

      We should prototype a snapshot model, when a set of classes are already loaded before the VM executes any bytecodes. This will allow us to skip a significant portion of the run-time checks.
