Migrate to Java 8 (sponsored contribution)

Browse Source 
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
