f50bef3eb2 Fix TCPShield compat by using raw address for sessions
TCPShield overwrites the IP address during connection. ProtocolLib
doesn't notice this change, because it uses the end-to-end connection
which is the proxy IP. This causes getAddress calls during Spigot play
state and ProtocolLib auth state not match and then have conflicting
session ids.

A solution is also to hold onto the temporary player object. However
since we don't get a notification for a disconnect, holding it will
prevent to get GCed until the timeout occurs (1 minute).

Fixes #595

7e9da9fd7c Migrate to Java 8 (sponsored contribution)
Java >8 includes many helpful features and API additions. Current
phoronix benchmarks indicated a very similar performance. Furthermore,
the fact that Java 18 even works with 1.8.8 contributed to the
decision to move to Java 17 like vanilla Java in 1.19.

This also helps us to learn about the newer features added for our
personal interests. As this is a free project, this motivated us to make
this step.

Nevertheless, many server owners were frustrated about this decision.
Thanks to financial contribution, we revised this decision until Java 8
is end of life or no longer used actively used according to bstats.org
