builtin class loaders and security manager

[Michał Zegan]

Hello,
I seem to be asking many questions lately, although I am actually
interested in some motivations. I was reading code of builtin class
loaders, and from what I understand from that, it seems that classes
loaded by builtin class loader including app class loader, if loaded
from a signed jar, are properly verified, however signers are not
retained in CodeSource. Is this intentional/why?
