BootClassLoader is not the boostrap class loader but instead it's implementation details.  The bootstrap ClassLoader instance is null and so you can’t invoke ClassLoader::getName.

OK.  At one point, that was how it was coded.

“<loader>//<classname>” is correct.

Make the output compact when it can, for example, the class loader name “app” and “platform” from classes from the JDK can be implied.

Maybe not much to add that.
