  `static Package` | Package.`getPackage​(String name)` | Deprecated. If multiple class loaders delegate to each other and define classes with the same package name, and one such loader relies on the lookup behavior of `getPackage` to return a `Package` from a parent loader, then the properties exposed by the `Package` may not be as expected in the rest of the program.
