But I have it first:

-vmoptions:"-XX:+UnlockExperimentalVMOptions -XX:+UseJVMCICompiler -Xcomp"

It's when I change -vmoptions to -javaoptions that it breaks. Seems to 
me, based on the error message:

 >> -XX:+UseJVMCICompiler -Xcomp -XX:+UnlockExperimentalVMOptions;

that jtreg has reordered things somehow ??
