Your (default) java version does not recognise the JDK 8 specific option MetaspaceSize and borks before tripping over the MaxMetaspaceSize option it also won't recognize.

You might have different JDK's installed with the default pointing to a JDK 6 or 7 and should try setting an explicit path to the correct java binary for your JDK 8 install.
