jtreg -vmoption(s) vs. -javaoption(s)

[Mike Duigou]

I'm trying to understand what differences in usage there are for the -vmoption and -javaoption flags. From my reading of RegressionParameters.getTestVMJavaOptions() it would seem than in practice the two options are interchangeable. Is there some other distinction I am missing? The command line help includes a see also for each to the other but doesn't explain any difference.
