Problem with vmoptions versus javaoptions

Thanks for adding the last line; it was important.
Yes, jtreg was trying to set up the command to get the custom property
definitions from the JVM under tests. This happens once, at the
beginning of the run.
I've not seen this "order of options" show up as a problem before.
In this case, the command line contains the following, in order,
1. the options specified by `-vmoptions`
2. by the options specified by `-javaoptions`
3. any additional options needed for the module system
4. any options specified in the "extraPropDefns" entries in TEST.ROOT
Can you use that information to ensure that the command line gets set up
correctly? At this point, I'm not sure if there is really a bug or not,
given Martin B's comment that this seemed to work for him. I would
strongly expect that if you put -XX:+UnlockExperimentalVMOptions early
in your -vmoptions you should be OK.
