java.desktop code calls several methods in sun.misc.ReflectUtil
ReflectUtil.checkPackageAccess - 18 uses
ReflectUtil.isPackageAccessible - 9 uses
ReflectUtil.forName - just one usage

After JEP 486 - "Permanently Disable the Security Manager" these were hollowed out.
The first two are now no-ops so can just be removed.
forName now just calls Class.forName() and since java.desktop uses the same classloader as java.base this is equivalent so can be collapsed to Class.forName directly
