One point where it's used is in java/lang/VMClassLoader to gather the
information about the boot packages.

Btw. HotSpot adds boot packages to the list when a class is loaded via
the bootstrap classloader.  So, the list does not contain all packages
at startup but grows during runtime.  Maybe this could be an
incompatibility somewhere, but I don't know what the spec says here.
