I don't know what webupd8 is but I assume you were testing with a Jigsaw 
EA builds [1] and have now switched to a regular JDK 9 download [2]. 
Yeah, it is confusing to have two downloads but having builds of the 
sandbox has been useful to try things. The Jigsaw EA downloads have the 
support for GNU style command line options and that support is in the VM 
too (that is why you have been able to use them with _JAVA_OPTIONS). We 
have not brought these changes into the JDK 9 main line yet so the main 
line is still on the old options (-addmods, -XaddExports, ...). We 
expect to bring the GNU style module options into JDK 9 in the coming 
weeks (exact build is TBD).
