Hey megdimka, next time just paste the error right into the comment box.

How often are you getting this error? Based on the output of the two errors it doesn't seem to make a difference whether or not vsync is enabled.

That error indicates that you are trying to run Mythruna with a newer version of Java than it supports.... probably Java 9?

Java 7 will work for sure.  Java 8 may work but I don't know.
