问题
I am trying to start a server using jre 10.0.1 64 bit. There is an obvious change in the settings for the JVM in windows start batch files. With the setting of -XX:+UseParNewGC as the reference point of the error what would this need to be changed to in order to get a JVM server start with java 10 versus the java 8 settings I have shown?
The line of code causing the error reference is:
set JAVA_PARAMETERS=-XX:+UseParNewGC -XX:+CMSIncrementalPacing -XX:+CMSClassUnloadingEnabled -XX:ParallelGCThreads=2 -XX:MinHeapFreeRatio=5 -XX:MaxHeapFreeRatio=10

This collectors was deprecated in JDK 9 and removed in JDK 10.

The new default is the G1 collector and I suggest you see if that suits your needs.

A follow up to Peter's answer, the flag is
-XX:+UseG1GC
as described at Oracle
