- The H2 files generated by plugins weren't accessible with 3rd-party tools (database viewers and such) because it referenced classes from the plugin - H2 now uses the raw H2 classes safely by loading into an isolated class loader (won't conflict with other plugins) - Any `RuntimeLibrary` can be loaded isolated now
