Definitely something not right here as it looks like a type defined to 
the boot loader that is in the unnamed package but it's module field set 
to java.base. It feels like a corruption issue, either that or somehow a 
type in the unnamed package was loaded really early (before java.base is 
defined) and has somehow been patched to in the java.base module.
