 # The UseExeperimentalVMOptions, UseCGroupMemoryLimitForHeap and MaxRAMFraction options that were used in the JDK 9 builds are
 # no longer supported in JDK 11 - so these have been removed. We now rely on the built-in ContainerSupport option that Linux JDKs
 # use to configure themselves when detecting they are running in a container.
