Changes:

• Experimental 1.17 support released
• Fixed a few 1.17 support issues
• Minor optimizations

Note!
you must run on normal versions of java (below java 16)
you can run a 1.17 server below java 16 using the parameters
from md5's 1.17 announcement, as 1.17 support is experimental let us know quickly of any issues you might find with it so we will be able to fix as asap
