Describe the bug
The server sometimes shuts down properly at improper times due to multiple OutOfMemoryErrors stating that the GC couldn't free enough heap memory. In addition, serious lag has been observed before that point (4,275.21% of normal tick time, so about 2 seconds per tick).

It was also noted that the server's maximum memory is around 1 GB while the parameters explicitly say 5 GB. Some other params aren't applied as well (possibly none).

To Reproduce
Steps to reproduce the behavior:

Play on the server, even generating new chunks and/or be near a village
Wait
Observe the TPS or wait for the server to run out of memory and restart

Expected behavior
The TPS stays at around 20 and the server doesn't have memory issues.

Screenshots

Additional context
I believe the sole reason is that the server params aren't applied - which is possibly a ServerRunner bug.
