I did try -Denable-preview=true -- BUT while that does allow "something"
to pass through jsvc parsing, it is not passed to the booting jsvm/tomcat
in any meaningful way. IE, the application fails to load with this error
still:
20-Mar-2020 14:03:25.804 SEVERE [main]
org.apache.catalina.core.StandardContext.filterStart Exception starting
filter [FrameSecurityFilter]
java.lang.UnsupportedClassVersionError: Preview features are not
enabled for com/bus/itm/empbc/FrameSecurityFilter (class file version
57.65535). *Try running with '--enable-preview*' (una
ble to load class [com.bus.itm.empbc.FrameSecurityFilter])
