RFR: 8223260: NamingManager should cache InitialContextFactory

Hi Seán,

If the TCCL is the key then there are good chances that the
concrete factory class is expected to be loaded by the TCCL.

If that happens then the value will reference the key and
nothing will ever get garbage collected.

So if I'm reading things rights this will not work as expected?

best regards,
