Is RuntimePermission.accessClassInPackage now redundant?

[Mike Hearn]

Hello,

I was reviewing the default security policy and noticed quite a few modules
are given accessClassInPackage permissions to e.g. packages in the sun.*
hierarchy. Are the SecurityManager/ClassLoader based package control still
needed now the module system has a built-in equivalent? I wasn't fully sure
if this is some sort of tech debt waiting to be cleaned up, or if these
permissions still have a role to play in the post-Jigsaw world?
